Meta-SPSS doesn't deal with zero

veronika
Hello,
I am using the Meta-SPSS tools for analysing my data.
I got problems with MetaAnalysisOfBinOutcomes(OR-Peto).SPS I am using because some p-values are zero. When I leave the conditions with p-vals zero out, everything works, so I don't think it's problem with my matrix. Anyone knowing help to avoid this?
Thanks. Veronika

Hi Veronica

v> I am using the Meta-SPSS tools for analysing my data.

I wrote META-SPSS, my e-mail address was given with the documentation,
try writing directly to me, because I have been out of the list for
some days (due to work), and I didn't spot your message till now.

First of all, there is a newer (improved) version of the code at
Devcentral:

(if requested to login, use both Guest as user and password)

The collection of syntax files have been amalgamated into a set of 3
macros, easier to use, and debuuged of some tiny errors the previous
version had.

What do p-values have to do with OR? Meta-analysis of p values uses a
different file. OR peto need raw data, not p-values. Please, explain
the problem with more detail (a sample of your data would be great)
and I'll try to help you.
