Hello,
A colleague has asked me about what flavor of linear regression to
use when the explanatory variable(s) are proportions. I know that
logistic regression handles situations when the *response* variable
is a proportion, but are there special considerations when the
explanatory vars are proportions (0 to 1)? I know that such vars
should be independent, and they cannot all be independent if they
sum to 1.
I would be grateful for your advice.
