Dear Allstat,
I am finding pronostic index score (PIS)for the cancer patients. i am using stepwise analysis final
model i forces to include age sex, stage, and performances score and albumin.
my questions is
1. Is it correct to forces variable which is not significant in the model
used to calculate PIS , even though non significant varible not include in
the scoring system.
2.albumin is related to stage , performances score and c-reative protein
is it correct to exclude these varible and include albumin
Thanks in advanced.
Paveen
