Use the name of the dependent var instead of "mean". You have used a special
syntax that is only applicable to -regress-

Betreff: st: suest followed by hausman

dear stata users:

i am interested in finding out whether the affects of one variable (adj_red)
on an individual's likelihood of being sentenced to incarceration (incar)
varies depending on whether or not the individual is being sentenced in a
state that uses sentencing guidelines (guidelines).  as such, i am using
suest followed by a a hausman test.  however, currently my code works until
i get to the test line, when i get the error: "equation [a_mean] not found /
r(303);".  interestingly, if i run this same code using reg instead of
logistic, the code works. 

what am i doing wrong?  the code is below.

thanks in advance for any feedback!

traci
