Variable types for regressions

[Ishto Stanfield]

Can anybody let me know what are the variable types on which a regression can run?

Ishto:
I'm not clear with the core of your query.
Anyway, if you mean regressands, they can be continuous (-regress-), categorical (-logit- and -logistic-) =>0 counts (-poisson-; -nbreg-).
