Dear Gretl users,
I'm trying to introduce an interaction in the next script.
ols SPEC const Var1 Var2 COV1 COV2 COV3 COV4 COV5 COV6 COV7
I like to introduce the interaction between Var1 and Var2. What is the
correct code?
Var1 is a two-levels factor and Var2 is a continuous predictor. SPEC is
the response variable and COV1...7 are control covariates.
Sorry Juan,
this is too gretl-unspecific for my taste. Do yo think you would be able
to specify an interaction effect in *any* econometrics software package?
Good luck and sorry again,
Sven
