Hello Fernando,
Thank you for your quick response.
I thought of this. Do you mean, that I should reshape my dataset in the following way?
year return std market_return
firm1 1985
1986
1987
firm2 1985
1986
1987
and then run a simple linear regression?
I tried different reshape commands-, but none of them seems to work..
