proc gampl logistic regression splines adjusted model

[ChristosK]

Having trouble with creating a fully adjusted logistic model using proc gampl at this stage:

We were trying to get a smoothed out spline figure for the adjusted model...

This is the error message:

NOTE: The SAS System stopped processing this step because of errors.

The only thing I just tried was adding param (   ) to the covariates in the proc gampl statement.

Any thoughts?

param (
Redo1 NIDDM1 COPD Hyperlip CHF Afib CM CAD MI AICD DDRF PVD BB Steroids Amio AA1 Statin1 Nitrates1 Diurectics1 IABP_ever1
/* Age pre_Na pre_BUN pre_Cr pre_Gluc pre_PTT pre_Neutro pre_Lymph pre_Hgb */
)

All of your predictors must be either in PARAM( ) or in SPLINE( ). None can be listed outside of one of those. Also, I assume your code actually says "proc gampl data=forgampl3" and that you didn't leave out "gampl".

Thanks Steve.

Yes it does. I had uploaded the code I had used in my original question but do not see it there now.

That happens alot when I start a new thread. It takes several attempts to get it to actually post.

Much appreciated.
