Thanks for confirming. This is what I had done.
Peter,
You can try:
bys firm: egen dispEdu = mean(abs(Edu_firm_level - Edu_ind_level))
Best,
Rafa

Do you know how I can avoid having the collinearity. I do want to show the dispersion of education and education amongst workplaces.
Many Thanks
Well, maybe it was defined by occupational groups ? Then it would vary

But another pper hd reported mean_deviation of education. This is just a
variable for dispersion of workplace education.
Thanks

Are they constants?
Dear Peter
We need a little more info to help you. E.g. what model are you
estimating ? With which data ? Which regression command ?
Best

Dear Statalist
Can anyone please tell me why when two median_deviations', that is,
median_deviationeducation and median_deviationtraining are used they are
dropped from a regression.
Thanks
