Hi,

Before I post my question, I would like to mention that I already looked through the forums here on using for loops to run multiple regression models (https://www.statalist.org/forums/for...-the-same-time, https://www.statalist.org/forums/for...le-regressions, https://www.statalist.org/forums/for...ssions-at-once). Unfortunately, the existing discussion posts don't quite answer my question.

My dependent variable is A. My independent variables are B,C,D,E,F,G,H. All these variables have been log transformed as well. So, I have ln_A and ln_B - ln_H. Now, I need to try different combinations of logged and non-logged variables and run multiple regressions. For instance,

Model 1: reg A ln_B ln_C D E F G ln_H

Model 2: reg ln_A B ln_C D ln_E F ln_G ln_H

and so on...

As you can tell, there are far too many combinations possible (P

Thanks in advance!

_{8,8}precisely?). I need to run at least a few different specifications. The reason for doing this exercise is to make sure that the polarity of the coefficients is not an artifact of the log-transformation. Is doing it manually the only way or is there a way to automate this? Please help!Thanks in advance!
