3. Overview Objective: To develop a web-based Statistical Analysis tool based on the statistics alumni information. Four Types of analysis will be performed, namely, Regression analysis, correlation analysis, hypothesis test, Chi- Square test. Stake Holders: Department of Statistics, Kansas State University Padmaja Havaldar, Department of computing and information Science, Kansas state university Use: The department will use the analysis as research to help make decisions for future Statistics students

4. Overview Features: 1. The members will be able to register online with the help of a form provided for this purpose. They will be able to add, delete or modify the data provided. 2. The website will perform analysis based on the research question selected 3. Each research question will perform the appropriate analysis 4. The results will be displayed in the form of Graphs/Tables 5. A list of all alumni will be made available 6. A search for a particular alumni will be made available

5. Project Requirements Login Provides member authentication Input is verified by checking the existence of the member in the database Registration Registration of a non-member. Input is validated using client side as well as server side validation. The client side validation will include checks for missing information in the required fields. The server side validation will involve checking if the username entered is already used by a member in the database.

6. Requirements- contd Statistical Analysis A research question is selected to perform analysis like regression. Depending on the research question, the appropriate statistical analysis is performed with the help of the EJB which provides the middle layer in this three tier application. The analysis can be regression analysis, correlation, hypothesis test or the chi square test. The output will be a graph or table of the analysis results displayed on the web browser page

7. Requirements- contd Performance Requirements Since the application will be displaying graphs for the analysis, the response time for a particular analysis should not be greater than 3-4 seconds for a respectable internet connection speed. The database should be scalable; it must have the capacity to hold large number of users in future. Assuming that the department uses this website for the next 20 years, the number of users will probably not exceed 2000. Oracle is scalable enough to meet these requirements for the next 20 years.

8. Use Case

9. Requirements- contd The data for the analysis will be obtained from the database of users, so the response time for a query from the client side to the database side should not be more than 1 second. Error handling should be implemented and the application should be able to handle all run time errors. The application should be flexible for future enhancements, for example, the addition of a few more research analysis questions

10. Cost Estimation The Cost and size of the project is estimated using Function point analysis Cocomo model

11. Cost Estimation Function point analysis Total UFP = 110 Product Complexity Adjustment (PC) = 0.65 + (0.01 *46) = 1.11 Total Adjusted Function Points (FP) = UFP * PC = 122 Language Factor (LF) for Java assumed as = 38 Source Lines of Code (SLOC) = FP * LF = 4636

12. Cost Estimation COCOMO TDEVProgrammer Productivity Development Time (Month) Application Programs PM = 2.4 * (KDSI) 1.05 PM = 2.5 * (PM) 0.38 Utility ProgramsPM = 3.0 * (KDSI) 1.12 PM = 2.5 * (PM) 0.35 System ProgramsPM = 3.6 * (KDSI) 1.20 PM = 2.5 * (PM) 0.32

17. Architecture Elaboration Plan Activities The documents presented during the phase I, which are the Software Requirement specification, Software Quality Assurance plan along with the changes will be documented. An updated time log will be documented. The vision document will be updated to ensure that the requirements specification have captured the driving requirements of the project. The updated version will be approved by the major advisor. Cost Estimation: The updated cost estimation will present the evaluated cost, size and effort for the statistical analysis tool. The revised version will be approved by the major advisor.

18. Architecture Elaboration Plan - contd The project plan will be updated taking into consideration any new milestones, corrected phases or iterations and deliverables along with the estimated completion date. The Implementation plan will define the activities and actions that must be accomplished during implementation. The plan will include a Work Breakdown Structure, with time and cost estimates and the completion criteria. The complete design of the project will be documented This will include class diagrams and object models along with any sequence or interaction diagrams. A section of the product’s design will be formally specified using OCL. A test Plan and Executable Architecture Prototype will be delivered A formal inspection by two MSE students will be conducted.
