A new extension command, STATS DISAGG has
been uploaded to the SPSS Community website. This command disaggregates
a time series into one at a higher frequency. For example, it could
create a quarterly version of an annual time series. It can use higher
frequency series that are correlated with the lower frequency series in
this process if available. There are a number of algorithms included
and several possible relationships between the input and output series
(sum, average, first, and last).
This command requires the R Essentials
and at least version 18 of Statistics. It can be downloaded from
within Statistics using the Utilities menu in version 22. Older versions
can download it from the SPSS Community website (www.ibm.com/developerworks/spssdevcentral)
in the Extension Commands collection.
