[R] How to validate model?

[Pedro.Rodriguez at sungard.com]

Usually one validates scorecards with the ROC curve, Pietra Index, KS
test, etc. You may be interested in the WP 14 from BIS (www.bis.org).

Subject: [R] How to validate model?

Hi!

I am working on scorecard model and I have arrived at the regression
equation. I have used logistic regression using R.

My question is how do I validate this model? I do have hold out sample
of 5000 customers.

Please guide me. Problem is I had never used Logistic regression earlier
neither I am used to credit scoring models.

Thanks in advance

Maithili
