Subject:      (Small) Time series: How to check if the values are significantly
              different?
Content-Type: text/plain; charset=us-ascii; format=flowed

Dear SPSS-fellows,

this seems to be a statistical and a SPSS-question:

I have aggregated data for 12 consecutive months. Some variables are
normally distributed on the aggregated level, others are not. I want to
know for each variable separately if the 12 values do differ
significantly from each other or not.

If I had a cross section, I knew what to do. But since I am not familiar
with time series data my question is: Which SPSS procedure do I have to
use for a little time series like this to test for differences?

Thanks for your help
Walter
