Time series analysis is something that pspp doesn't yet have much of. You might
have to use R or Gretl instead.
However you could, for example, examine the correlation between time/date and
the
frequency of a particular tag. In that case, you might want to use the
AGGREGATE
command to create a running total of the tags.
But before you start doing that, you need do decide what you hope to find in
the
data. In other words what is your hypothesis? Only then can you decide on
how to analyse the data.

I need to use PSPP to analyse some data for a report I need to write for a

is capable of doing. I want to analyse the use of tags on a weblog over a
period of years, frequency of each tags use and some sort of representation
of the use of each tag over time. Below is a very simple representation of
my data in PSPP. Posts listed on the left column, then date of post and
then codings for tags (if a tag is used 1, if not used 0):
Post Names date tag1 tag2 tag3
--------------------------------------------------------------
Post 1 12-AUG-2013 1 0 1
Post 2 19-JUN-2013 0 0 1
Post 3 06-MAY-2013 1 1 0
How can I show the use of the tags over time - what analysis should I be
focusing on? Perhaps I'm structuring my data all wrong and should be
putting tags in the left column with simply a post count after date? Like
so:
Tag Names date Post Count
-------------------------------------------------
Tag1 12-AUG-2013 2
Tag2 19-JUN-2013 1
Tag3 06-MAY-2013 2
Any help much appreciated.
