You need to show what you did and what came of it in order to get an answer.

The fact that your post got through is proof that you are still included.

Betreff: st: Help needed for Poisson regresion

Can anyone help me clarify the doubt regarding the coding pattern. I am
trying to run a Poisson regression with Incidence rate Ratio for diarrhea
for a CASE and CONTROL study.

Earlier I put code 1 for the CASE and 2 for CONTROL. Later I changed the
code as 1 for CASE and 0 for CONTROL. Due to this I saw the change in the
results. Can anyone suggest me what is the correct way of assigning codes to
the dependent and independent variable.

any reference for interpretation of the results will be mush helpful. Please
Cc the response to my email ID also as I am not sure if my email ID is still
included under the forum.

Thanks
Priyajit
