Dear Statalisters,

I appreciate very much your assistance in the following question:,

I'm looking for an equivalent function for -gen y1=sum()- which will
calculate running product for each point in time

In fact, what I would like to calculate is a running geometric mean

Note also that -gen y2=prod()- does not work (i.e., stata does not
identify the function). Only -egen y2=prod()- works, but it generates
only one product for each panel, and this is not what I need.

Finally, I tried the -amean- command,, but it simply gives summary
statistics of different means, and it is not a function..
