Re: st: Software for Epidemiological, Longitudinal Data

[Marcello Pagano <pagano@hsph.harvard.edu>]

A quick search of the New England Journal of Medicine site reveals 
partly similar results:
Since July 1996:

SAS    458 articles
Stata   160  ...
SPSS  140 ...

I stress quick because I did not check each article to see if some may 
have been referring to the Scandinavian Airlines or not, or a building 
at MIT etc...  But if one is to look a little into these numbers and 
shorten the timespan to be more recent, say:
Since July 2000:

SAS    298 articles
Stata   132 ...
SPSS  100 ...

and even more recently:
Since July 2004:

SAS   107 articles
Stata    87  ...
SPSS  33  ...

Perchance evidence of Sebastian's trend??
What the hey, let's look at the last year:
Since July 2005:

SAS    55  articles
Stata   72   ...
SPSS  14  ...

Hmmm   Should I have reported,

Stata  72 articles
SAS   55 ...
SPSS 14 ... ?
