Subject: Re: Analysis of categorical data - is Chi-Square my only option?

You are absolutely correct - my vocabulary may be my undoing here. I
guess the ultimately question is, when looking at my population, I
want to see what variables have a significant relationship (or effect)
with the "quit" variable. That is why at first I was using
Chi-Squares, but since I am looking at 6 or so influencing the "quit"
variable, it gets cumbersome.
I was wondering (hoping) if there was a "kitchen sink" approach that
throws all of them in the pot and comes back with what matters and
what does not.
Thanks for the help.
