Re: Help with course work

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
     course but I'm having trouble matching up what I want to do with what PSPP
     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.
