Dear Statausers,

I have found xi3 extremely useful for regressions with
interaction terms. However I am not able to use xi3
with the probit command.

Y = b + b1X1 + b2X2 + b3X1X2

I get the message too many variables.
How many variables are being created? Perhaps you are hitting some sort of system limit. Also, do you get the same error with -xi-? Knowing this would help to determine whether it is a problem specifically with -xi3- or whether it is some broader issue.
