Dear All Greetings,  I had collected data from 260 respondents data in PASW 18 my QUSEIONNAIRE had 125 INDEPENDANT VARIABLES AND 1 Depandant variable(dichotomous). Is it Mandatory for me to do data reduction(Factor analysis) before making model? or should i use all the independant variables and let my software take care of rest and develop a logistic model for me( Stepwise) and (Enter). I think that if i dont do data reduction it wont affect my results to a large extent. Any other recommended method of model development? Thanks. Sincerely Khizar(Researcher)
