Final Model after considering transformations.
Introduction.
A simple example, diabetes and gender.
Examining age and male interactions.
Variable selection with interaction terms.
Final model with interaction terms.
A different approach is to consider all interactions.
Homework
Come to closure with the lipid2018_b data set -- submit a final model based on this data.
NOTE:
The submission for this homework should be a text document (word, rtf, plain text, etc.). It should in the form of a report and include the programs you used. In this report explain the methods used for coming to closure and what decisions you made.
