You might want to look at the CCF procedure
---
*CCF*
*Overview*
*CCF * displays and plots the cross-correlation functions of two or more
time series. You can
also display and plot the cross-correlations of transformed series by
requesting natural log and
differencing transformations within the procedure.
*Options*
*Modifying the Series*. You can request a natural log transformation of the
series using the LN
subcommand and seasonal and nonseasonal differencing to any degree using the
SDIFF and
DIFF subcommands. With seasonal differencing, you can also specify the
periodicity on the
PERIOD subcommand.
*Statistical Display.* You can control which series are paired by using the
keyword WITH. You can
specify the range of lags for which you want values displayed and plotted
with the MXCROSS
subcommand, overriding the maximum specified on TSET. You can also display
and plot values at
periodic lags only using the SEASONAL subcommand.
