Multiple Regression Basic assumptions Linearity X is an n by K matrix with rank K Regression Homoscedasticity

4
Multiple Regression Hypotheses By ANOVA When the null hypothesis is rejected, For all i.

Multiple Regression Standard error of coefficient

9
Canonical Correlation Correlation structure between a group of independent variables and a group of dependent variables A kind of multiple regression with more than two dependent variables Example: Physical size group vs. Exercise group How much explained the variation of a group of variables by other group of variables?
