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
