Complex Data Sets
These data sets are more complex than the ones used for weekly assignments. They
were used for the two projects given at midterm and for the final takehome exam.
Students were required to assimilate all the material covered in the course and
to make various decisions affecting the course of the analysis, such as which
covariates to drop, which to transform, which hypotheses to test. Decisions made
early in the analysis could lead to very different final models. The students
needed to remain aware of their aims and to determine whether the final model
achieved these aims and led to a meaningful interpretation.
