Dear All - I have a stats question concerning comparing linear
regressions. If you have two or more regressions, and want to know if
their slopes and/or intercepts are significantly different, what
procedure would you use? I am familiar with SAS mainly. Zar has a
two-sample t-test equivalent for comparing two slopes, but the procedure
for intercepts is extremely cumbersome, as is the multiple slope
comparison, which involves ANOCOVA.
Thanks!
