GLM, etc.

[gaffney2010]

Per Dan:

Add multivariate GLM part to visualize predicted values, taking into account correlations

We should also look at using/testing polynomial (rather than just linear) regression for our continuous variables

Think about simplifications of variables.. Is there a way to automate this part. At very least, do forward/backward regression with
a linear model to see if strange/undesireable things are happening.
