Subject: Re: How Stepwise Regression works in SAS?
Hallo,
I Agree that Stepwise is a technique that should not be used in almost any
kind of Statistical Modelling, and I Think that apart from think a lot about
the problem and about what you trying to predict, descritive statistics is
Crucial.
I Started Working in a Financial Institution recently, and we usually do
Models for Application Scoring. In the first Analysis of the variables, I am
thinking of some Chi-Square Independence tests for the Categorical Variables
vs performance of the Applicant (Good/bad) and some non-parametric bootstrap
model Comparison for the continuous variables vs performance, but I Wonder
if it is really a right approach. Some Comments would be very helpful.
