In this course, we will learn what happens to our regression model when these assumptions have not been met. How can we detect these discrepancies in model assumptions and how do we remediate the problems will be addressed in this course.
Upon successful completion of this course, you will be able to:
-describe the assumptions of the linear regression models.
-use diagnostic plots to detect violations of the assumptions of a linear regression model.
-perform a transformation of variables in building regression models.
-use suitable tools to detect and remove heteroscedastic errors.
-use suitable tools to remediate autocorrelation.
-use suitable tools to remediate collinear data.
-perform variable selections and model validations.
