# Regression Analysis

Simple regression analysis, multiple regression analysis, matrix form of the multiple regression model, estimation, tests (t- and F-tests), multicollinearity and other problems encountered in regression, diagnostics, model building and variable selection, remedies for violations of regression assumptions. First term.
This course is closely linked with MATH3034 3.0, Applied Categorical Data Analysis, for which it is a prerequisite. Students will use the computer heavily in these courses, but no previous courses in computing are required.
MATH3330 3.0 will focus on linear regression models for the analysis of data on several explanatory variables and a single response. The emphasis will be on understanding the different models and statistical concepts used for these models and on practical applications, rather than on the formal derivations of the models. The approach will require the use of matrix representations of the data, and the geometry of vector spaces, which will be reviewed in the course. Topics include simple linear regression, multiple linear regression, residual analysis and model selection.
The nature of the course requires that students be involved on a constant basis with the material, and not fall behind.
The text and grading scheme have not been determined as we go to press.
