One way

. help egen

Use -rownonmiss()- across variables; then -total()- by panels.

egen mpresent = rownonmiss(y x1 x2 x3 x4)
egen npresent = total(mpresent == 5), by(panelid)
keep if npresent == 24

I am working on panel data (N=204, Ti = 1985...2008)
I would like to identify and keep panels which have the same time spell (on
a set of dependent variables and key covariates).
How could I proceed on Stata 12
