Hey David,

I am trying to do a basic linear regression. My variables are
variance of ground-cover and variance of topography. All I want to
determine is if topographic variance is a good predictor of ground-
cover variance, i.e. does a high topo variance value do a good job of
predicting a high ground-cover variance value? You don't think
REGRESS is the way to go?

Thanks

Annie
