Thanks. But when I use tssmooth, I am told there are
repeated time values in sample:

tssmooth ma st_7 = st, window(7 1)
repeated time values in sample

I have a number of cases for each time period. Any way
to get around this?


You need to tsset your data with both the individual and time  
indicator, e.g.

webuse grunfeld
tsset company year

Then tssmooth will operate separately on each panel within the  
dataset (as will egen filter).
