Dear statalist,

I am using the user-written command -psmatch2- (written by Leuven and Sianesi, 2003) to estimate the ATT of my participation variable on several outcome indicators. I am also using a DiD-regression approach to estimate the ATT where I transformed some of the indicators into logs to see the percentage change caused by the treatment. I wonder whether it is also reasonable to transform the outcome indicators into logs when running -psmatch2-. Can someone give me a quick hint? Thanks!

Best, Lukas
