st: interpretation of interaction terms

[Shehzad Ali <sia500@york.ac.uk>]

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
