[R] regression with limited range response

[Peter Flom]

Kim

This would depend a lot on how the DV is distributed within the 0-100
range.  It's even conceivable that the usual linear model could be used
without much problem (e.g. if the mean is 50 and the sd is small, then
the bounds of 0 and 100 will exist more in theory than in practice; of
course, you'd still want to do a lot of diagnostics).  

0 to 100 makes me think of a percent, there are methods for dealing
with percents.  

More generally, you may want to look at 
Long, JS (1997). Regression Models for Categorical and Limited
Dependent Variables. Sage.

which I find useful frequently.
