Dear all,
Does anyone know of a calculation or computer package that would let me
compare the R square values of two separate regressions to see if they are
significantly different.
I have carried out two regressions on the same dataset predicting
behaviour and I want to see if one of my models was signifcantly better
than the other one. I can't use R square change because I am using two
different behaviours (use of 2 different drugs) and different variables to
predict each behaviour (e.g. attitude towards drug A amongst other
variables to predict use of Drug A, and attitude towards drug B amongst
other variables to predict sue of drug B).
Thanks in advance,
Brian
