st: Use of data originating from SPSS - update

[Margaret MacDougall <Margaret.MacDougall@ed.ac.uk>]

Hello

I grabbed a spare moment to dip into a Stata manual on my journey home 
from work today and noted that for a logistic regression analysis, Stata 
requires one of the categories of my dependent variable to assume the 
value '0'. This pointed to a very simple solution (which worked) while 
highlighting a necessary change which needs to be made in the transition 
from SPSS to Stata which I was previously unaware of.  Creating a new 
coding in SPSS for the categories of the dependent variable while saving 
the modified SPSS file in Stata format did the trick.

Best wishes

Margaret
