4 About JMP® JMP was developed by SAS Institute Inc., Cary, NC
Using JMP statistical software, you can Interact with your graphs and data to discover patterns and relationships in your data See how the data and the model work together to produce the statistics Perform statistical summary and analysis

5 JMP Download and Installation
JMP license information All Virginia Tech researchers may download JMP free of charge by going to the Software Distribution Office's Network Software page and logging on using your PID and password JMP 9 is available now for both Windows and Mac Unzip the JMP 9 file, click on the ‘setup’ icon, and follow the instructions for installation

6 Prerequisites Before you begin using JMP, note the following information: You can use many JMP features, such as data manipulation, graphs, and scripting features, without any statistical knowledge A basic understanding of basic statistical concepts, such as mean and variation, is recommended Analytical features require statistical knowledge appropriate for the feature

7 JMP Terminology JMP platforms use these windows:
Launch windows where you set up and run your analysis Report windows showing the output of your analysis Report windows normally contain the following items: A graph of some type (such as a scatterplot or a histogram) Specific reports that you can show or hide using the disclosure button Platform options that are located within red triangle menus

10 JMP Data Table You can enter, view, edit, and manage data using data tables In a data table, each variable is a column, and each observation is a row To create a new data table: Select File > New > Data Table Ctrl + N Click on the first icon below the File menu

11 JMP Data Table This shows an empty data table with no rows and one numeric column, labeled Column 1

12 Entering Data Manually: Construct a formula to calculate column values
Move the cursor onto a cell, click in the cell and enter a value Construct a formula to calculate column values Open the formula editor by right-clicking the column name to which you want to apply the formula and selecting Formula… Or Double-click the column name to which you want to apply the formula, Column Properties > Formula > Edit Formula Select an empty formula element in the formula editing area by clicking it

13 Importing Data You can import many file formats into JMP by default. For example: Comma-separated (.csv) .dat files that consist of text Microsoft Excel 1997–2003 (.xls) Plain text (.txt) SAS versions 6–9 on Windows (.sd2, .sd5, .sd7, .sas7bdat) SPSS files (.sav) Other files, such as Microsoft Excel 2007 files, require specific Open Database Connectivity (ODBC)

14 Import from Excel Files
File > Open or Ctrl + O or Or, select all data in the excel spreadsheet, copy, switch to JMP, create a new data table, Edit > Paste with Column Names Exercise: Open the SAT.xls excel file in JMP In the Open Data File window, change ‘All JMP Files’ to ‘All Files’ Copy and paste data in SAT.xls to a JMP data table

15 Data Table Panels There are three data table panels
Columns panel Rows panel The data table panels are arranged to the left of the data grid These panels contain information about the table and its contents

16 JMP Modeling Types The modeling type of a variable can be one of the following types, shown with its corresponding icon: Continuous Ordinal Nominal When you import data into JMP, it predicts which modeling types to use Character data is considered nominal Numeric data is considered continuous To change the modeling type, click on the modeling type icon next to the variable and make your selection

17 Access Sample Data Tables
All of the examples in the JMP documentation suite use sample data. To access JMP’s sample data tables, Select Help > Sample Data. From here, you can: Open the sample data directory Open an alphabetized list of all sample data tables Search for a sample data table within a category Alternatively, the sample data tables are installed in the following directory: On Windows: C:\Program Files\SAS\JMP\9\Support Files <language>\Sample Data On Macintosh: \Library\Application Support\JMP\9\<language>\Sample Data

18 Saving JMP Sessions A saved session can help get you back to a previous state without having to manually re-open files and re-run analyses Select File > Save By default, JMP asks whether you would like to save the state of your session each time you exit the program Saving session upon exiting:

59 Outline Introduction Getting Started Managing Data Visualizing Data
Creating Summary Statistics Performing Basic Statistical Analysis Saving and Exporting Results Resources

60 Numerical Summaries of Data
To general numerical summaries of data, you can: Create a table that contains columns of summary statistics Tabulate data so it is displayed in a tabular format

61 Summarizing Columns The Tables > Summary command calculates various summary statistics, including the mean and median, standard deviation, minimum and maximum value, etc. Select Tables > Summary Select the columns you want to summarize in the Select Columns box A new data table is created to store all the summary statistics requested but it is not saved when you close it unless you select File > Save As to give it a name and location

62 Summarizing Columns Exercise: Create summary statistics for SAT Verbal
Open SAT data Select Tables > Summary Click SAT Verbal near upper left Click Statistics button and choose Mean Can choose any statistic Can choose more than one statistic – click Statistics again Click OK

63 Tabulating Data Use the Tables > Tabulate command for constructing tables of descriptive statistics The tables are built from grouping columns, analysis columns, and statistics keywords Through its interactive interface for defining and modifying tables, the Tabulate command provides a powerful and flexible way to present summary data in tabular form Examples of summary tables:

64 Tabulating Data To create a summary table using the Tabulate command is an iterative process: Click and drag the items (column name from the column list or statistics from the keywords list) from the appropriate list Drop the items on the dimension (row table or column table) where you want to place the items’ labels After creating a table, add to it by repeating the above process

65 Tabulating Data When you drag and drop a variable, JMP populates the table automatically for it if its role is obvious, such as keywords or character columns Otherwise, a popup menu lets you choose the role for the variable Add Grouping Columns – if you want to use the variables to categorize the data. For multiple grouping columns, Tabulate creates a hierarchical nesting of the variable Add Analysis Columns – if you want to compute the statistics of these columns

66 Tabulating Data Exercise: Create descriptive statistics for SAT Math by Region Open SAT data Select Tables > Tabulate Click Region and drag and drop it into the Drop zone for columns Select Add Grouping Columns Click Mean and drag and drop it into the first blank cell on the third row Click Std Dev and drag and drop it just below Mean

67 Tabulating Data Exercise: Create descriptive statistics for SAT Math by Region

69 Types of Data Analysis One variable (univariate)
Distribution Two variables (bivariate) Fit Y by X More than two variable Fit Model More advanced features Modeling

70 Comparing Means One-Sample t-Test
Data: Help > Sample Data > Fitness Linneruds Fitness data: fitting oxygen uptake to exercise and other variables. The original is in Rawlings (1988), but certain values of MaxPulse and RunPulse were changed for illustration. Names and Sex columns were contrived for illustration

71 Comparing Means One-Sample t-Test Example: Fitness
Select Analyze > Distribution Select RunPulse > Y, Columns Click OK ▼ Red triangle menu next to RunPulse > Normal Quantile Plot ▼ Red triangle menu next to RunPulse > Continuous Fit > Normal ▼ Red triangle menu next to Fitted Normal > Goodness of Fit ▼ Red triangle menu next to RunPulse > Test Mean Enter 170 for Specify Hypothesized Mean to test if RunPulse equals 170 Prob >|t| is , there is not enough evidence to reject the null hypothesis

72 Comparing Means Paired t-Test – used when you have two related measurements Create a new column for ‘difference’ Select Cols > New Column Type Difference in the Column Name box Select Cols > Formula Select col 1 Select the subtraction sign Select col 2 Click OK Then perform the same procedures as for One-Sample t-Test Or, select Analyze > Matched Pairs

73 Comparing Means Two-Sample t-Test – used when you compare the means of two populations Example: Fitness Select Analyze > Fit Y by X Choose Sex > X, Factor Choose RunPulse > Y, Response Click OK ▼ Red triangle menu next to Oneway Analysis of RunPulse by Sex > Normal Quantile Plot ▼ Red triangle menu next to Oneway Analysis of RunPulse by Sex > UnEqual Variances ▼ Red triangle menu next to Oneway Analysis of RunPulse by Sex > Means/Anova/Pooled t (for unequal variance select t-test) Prob >|t| is , there is not enough evidence to reject the null hypothesis

74 ANOVA One-Way ANOVA with two groups – used when you compare the means of two populations Same as Two-Sample t-Test

75 ANOVA One-Way ANOVA with more than two groups –
used when you compare the means of more than two populations Example: Help > Sample Data > Car Physical Data Select Analyze > Fit Y by X Select Country > X, Factor Select Weight > Y, Response Click OK ▼ Red triangle menu next to Oneway Analysis of Weight by Country > Normal Quantile Plot ▼ Red triangle menu next to Oneway Analysis of Weight by Country > UnEqual Variances

76 ANOVA One-Way ANOVA with more than two groups
Example: Car Physical Data (cont.) - Residuals ▼ Red triangle menu next to Oneway Analysis of Weight by Country > Save > Save Residuals Rename Weight centered by Country as residual Select Analyze > Distribution > residual > Y, Columns > OK Select Continuous Fit > Normal > Goodness of Fit ▼ Red triangle menu next to Oneway Analysis of Weight by Country > Means/ANOVA Prob > F is , this is strong evidence for concluding that at least one mean is statistically different from one of the other means

77 ANOVA One-Way ANOVA with more than two groups
Example: Car Physical Data (cont.) – Contrasts ▼ Red triangle menu next to Oneway Analysis of Weight by Country > Compare Means > Each Pair Student’s t The diamonds for 1 and 2 overlap – they probably are not different; 2 and 3 do not overlap – probably different The circles cannot be interpreted unless you interact with them – select a comparison circle to highlight it ▼ Red triangle menu next to Comparisons for each pair using Student’s t > Different Matrix ▼ Red triangle menu next to Comparisons for each pair using Student’s t > Detailed Comparisons Report

78 ANOVA One-Way ANOVA with more than two groups
Example: Car Physical Data (cont.) – Contrasts ▼ Red triangle menu next to Oneway Analysis of Weight by Country > Compare Means > All Pairs, Tukey HSD Use this test to control the experimentwise error rate at the significance level α (e.g. α=0.05)

79 ANOVA N-Way ANOVA – used when there are more than one categorical factor Example: Car Physical Data Select Analyze > Fit Model Select Weight > Y Select Country, Type > Macros > Full Factorial Click Run ▼ Red triangle menu next to the response > Factor Profiling > Interaction Plots ▼ Red triangle menu next to the two-way interaction > LSMeans Plot p-values for the interactions is smaller than 0.05; not all the lines in interaction plots are parallel – conclude there is a significant interaction between the factors

80 ANOVA N-Way ANOVA Example: Car Physical Data – Contrasts
▼ Red triangle menu next to Country*Type > LSMeans Contrast Select the plus sign for USA, Compact; the minus sign for USA, Sporty > Done Prob > F is 0.03 – A US made sporty car is heavier than a US made compact car Select the plus sign for Japan, Sporty; the minus sign for USA, Sporty > Done Prob > F is 0.01 – A US made sporty car is heavier than a Japan made sporty car

81 Regression Simple Linear Regression – used to assess the significance of the predictor in explaining the variability in the response Example: Help > Sample Data > Fitness Select Analyze > Distribution Select Age, Shift-click MaxPlus > Y, Columns > OK Hold down Ctrl and click ▼ Red triangle menu next to Age > Display Options > More Moments Hold down Ctrl and click ▼ Red triangle menu next to Age > Normal Quantile Plot Hold down Ctrl and click ▼ Red triangle menu next to Age > Continuous Fit → Normal

82 Regression Simple Linear Regression Example: Fitness (cont.)
Select Analyze > Fit Y by X Select Oxy > Y, Response Select Age and hold down Shift and click MaxPulse > X, Factor Click OK Select Oxy, Remove from X, Factor Hold down Ctrl and click ▼ Red triangle menu next to Bivariate Fit of Oxy By Age > Density Ellipse > 0.95 Hold down Ctrl and click ▼ Red triangle menu next to Bivariate Fit of Oxy By Age > Fit Mean Hold down Ctrl and click ▼ Red triangle menu next to Bivariate Fit of Oxy By Age > Fit Line

83 Regression Multiple Linear Regression – used to model the relationship between many continuous predictors and a single continuous response Example: Help > Sample Data > Fitness Select Analyze > Fit Model Select Oxy > Y Select Age and Shift-click MaxPulse > Add Select Oxy, Remove from Model Effects Run ▼ Red triangle menu next to Response Oxy > Save Columns > Residuals Rename Residual Oxy as residual Select Analyze > Distribution > residual > Y, Columns > OK Select Continuous Fit > Normal > Goodness of Fit

84 Regression Multiple Linear Regression
Example: Fitness (cont.) – Model selection ▼ Red triangle menu next to Response Oxy > Model Dialog Select RstPulse from the Model Effects list and select Remove Run Select Weight from the Model Effects list and select Remove

85 Regression Multiple Linear Regression
Example: Fitness (cont.) – Model selection Select Analyze > Fit Model Select Oxy > Y Select Age and Shift-click MaxPulse > Add Select Oxy, Remove from Model Effects Select Standard Least Squares > Stepwise Run Direction: Forward > Go Run Model Direction: Backward > Enter All > Go

86 Regression Multiple Linear Regression
Example: Fitness (cont.) – Add interaction and higher order terms Select Analyze > Fit Model Select Oxy > Y Select Age and Ctrl-click Runtime and RunPulse > Macro > Factorial to degree (2 is used here) Run Select Age and Ctrl-click Runtime and RunPulse > Macro > Polynomial to Degree (2 is used here)

87 ANCOVA A model relating a categorical predictor and a continuous covariate to a single continuous response is known as an analysis of covariance (ANCOVA) model ANOVA with categorical and continuous predictors First of all, need to identify if there is interaction between predictors Example 1: DrugLBI – no interactions Data: Help > Sample Data > DrugLBI Notes: From Snedecor and Cockran, Statistical Methods, 1967 Use Fit Model with 'LBS' as response (Y), 'Drug' and 'LBI' as effects (Xs)

88 ANCOVA Example 1: DrugLBI – no interactions
Select Analyze > Fit Model Select LBS > Y Select Drug, LBI > Macros > Full Factorial or Factorial to Degree Click Run P-value for Drug*LBI = , greater than 0.05, indicating that Drug*LBI is not significant, thus can be removed from the model Examine the interaction in the Regression Plot: A linear regression line is drawn with a different color for each level of Drug. It may be difficult to interpret this graph for statistical significance of the interaction

89 ANCOVA Example 1: DrugLBI – no interactions
Re-do the analysis without including the interaction term Select Analyze > Fit Model Select LBS > Y Select Drug, LBI > Add Click Run Effect Tests report that Drug is not significant (p-value = ), and LBI is significant (p-value < ); it appears that there is no difference among Drug types in the response LBS

90 ANCOVA Example 2: Sawblade – model with interaction Data: Notes:
Import Sawblade.xls file to JMP Notes: Fit a model to study the effect of blade material and blade speed on heat generation

91 ANCOVA Example 2: Sawblade – model with interaction
Select Analyze > Fit Model Select Heat > Y Select Material, Speed > Macros > Full Factorial or Factorial to Degree Click Run p-value for the interaction term Material*Speed < , which is significant When there is a significant interaction, we cannot make a conclusion about Material or Speed along; the effect of Material depends on the Speed of the blade To interpret the interaction, look at the Regression Plot: A linear regression line is drawn with a different color for each level of Material

92 Saving Analyses to Data Table
To re-produce the previous analysis when you re-open the data table, you can: ▼ Red triangle menu > Script > Save Script to Data Table Re-produce the analysis from Data Table by ▼ Red triangle menu > Run Script
