Hi everyone
I was hoping you could give me some advice
I am trying to interpret a regression model in which the dependent
variable has been transformed because the original data was right-
skewed
The predictors are 1 continuous variable (age) and several dummy
variables (0/1) as well as some interaction terms between the dummy
variables
Is there a difference in the way these interactions are interpreted as
a consequence of the dependent variable being log-transformed?
Thanks!

There was no need to transform the dependent variable for the purposes
of regression analysis. It is the residuals that have to be normally
distributed, not the data itself.
