I have what I thought was an unremarkable panel data set containing monthly
performance data for 300 employees for 36 months. There is sporadic missing
data and not everyone starts in month 1 or finishes in month 36.
I am having trouble using the " tssmooth ma " command. Specifically, if I type
tssmooth ma foo=performance, window (1 1 1)
then the result makes good sense.
But any use of lags or leads great than 1 results in the same error. For
example
tssmooth ma foo=performance, window (2 1 2)
leads to the message
window( ) invalid -- invalid numlist has elements outside of allowed range .
The manual tells me that the first and third arguments can accept integer
values ranging from 0 to one-half the number of observations in the
sample. What's wrong here?
Thanks,
Chip Hunter
