Dear all,
I want to produce a file with the autocovariance matrix of wage for 7 subsequent years. I have my data organized in such a way that I have one income variable per year, so the wage variables in my dataset are:
lhwage1995 lhwage1996 lhwage1997 lhwage1998 lhwage1999 lhwage2000 lhwage2001
Then, I run:
statsby ,by(country) clear: corr lhwage1995 lhwage1996 lhwage1997 lhwage1998 lhwage1999 lhwage2000 lhwage2001, covariance
But then I get a dataset where only the covariance between lhwage1995 lhwage1996 for every country is saved. The rest of the covariances disappear. Do you know how can I solve this? The `by' option is not the one creating the problem. I tried to remove it but things didn't change.
I would appreciate your help.
best regards,
Dimitris
