Hey everybody, I have a variable (year) that I was supposed to include in my regression model as a fixed effect. I just found out that it is heavily right-skewed(most observation in the last 4 years of sample period of 20 years) and ruins my model fit. Every other control variable, that is...
I´m running a linear regression model. The variable I want to use to build the subsample is binary (either 0 or 1).
Edit: I think it´s easier to show what I mean with two screenshots. I want to test whether the difference in the two estimates of POST =1 is statistically significant.
Hey everyone. I am currently doing some regressions for subsamples of my original sample where an indicator equals 1 for the first regression and 0 for the second regression. What test do I have to use, to test for the significance of the two resulting coefficients?
