Subject:      Log transformations: dummy variables
Content-Type: multipart/alternative;


Hi all,
 
I have to perform a regression analysis and when performing the analysis with the normal data I get a scatterplot which could indicate heteroscedasticity.
So I decided to transform the data by logging everything, however I have quite a gew dummy variables. My questions are:
1. Do I also log dummies (after adding 1)?
2. Do I have to log all the continous variables or can I only log the dependent variable?
3. How do I interpret the results?
 
Any help would be greatly appreciated.
