I have one data set consisting of 2 groups.  Group 1 f=1 and Group 2
f=0.  I am looking to compare parameter estimates for these two groups
with a Wald Chi-square test statistic.  Can someone specify how I'd go
about doing that?

For example, right now my code for the regression looks like this:

proc reg data=gg11;
model retpi = dummy; by f; run;

what I need to do is compare the coefficient on dummy for when f=1 and
when f=0 using a wald test. Thanks in advance for any help!
