Yes, but I think the basic understanding or interpretation of
regression coefficients for continuous or binary variables is not
altered when a variable has been log transformed. It is true that
interactions can be present or absent depending on whether or not a
variable has been transformed, because interactions are scale dependent.

Hi,
Could someone please help me interpret the following:
1. Coefficient on an interaction term for a dummy and log-
transformed variable in an OLS model when the dependent variable is
in natural units or is also log-transformed
2. Coefficient on an interaction term for an untransformed
continuous and log-transformed variable in an OLS model when the
dependent variable is in natural units or is also log-transformed
3. Coefficient on an interaction term between a dummy and log-
transformed variable in a probit regression
Thank you,
Shehzad
