Transformations HW

Hi - have had a couple of questions about the hw for Tuesday, so I thought I'd clarify:

-Run 3-4 models, using a non-normal outcome that has been transformed 3 different ways (one model though should be with the untransformed version)
-Include covariates in these 3-4 models
-Examine residuals for each of the models.
-Table of the 3-4 models
-Write up - what you're presenting; describe the results including r2 and coefs; describe residuals- mean, min,max, distributions.
