st: mvsumm

["Kiousis, P. Konstantina" <kiousis_1@cob.osu.edu>]

Dear Statalist,
I am trying to use mvsumm but am getting an error of "too many values."  I have a panel with 657,987 observations, 20,197 unique id's and 76 quarters.  After tsset id quarter and tsfill to deal with gaps, I typed
 
mvsumm  d_rev,  stat(sd)  win(20)   gen(sd_d_rev)
 
Any advice would be helpful.  Thanks a bunch, KK
