I'm running cross-correlations to test on two time series to check fit at different lags. Most of my "fit" lags have been small (<15 periods), but one was a 22 period lag and I was looking to validate using a cross-correlogram. I put in 36 as the number of lags to run, but the resulting table only shows 19 lags. Is there a reason for this or is this something I can change to display more lag periods in the table (see attachment).

Thanks!!

You only have 21 observations. You can't show 36 lags if you only have 21 observations.

Ah, of course. I was looking at the longer time series in my group (48 observations) rather than the shorter one. Thanks!
