Proc Hplogistic and Splines

[davis]

I am new to hplogistic, and was wondering if it possesses the capability to specify splines for continuous covariates?

If so, pointing me in the right direction, providing a reference, or sending a link would be much appreciated.

Thanks.

You would need to use Proc LOGISTIC instead and invoke the EFFECT statement.

Proc HPLOGISTIC because of its high performance capabilities cannot add spline effects.

Thank you.
proc logistic/effect statement is where I started. runs fine, but relatively slower than proc hplogistic.

Use PROC LOGISTIC or PROC GLMSELECT to generate the spline effects and to output the design matrix, then use HPLOGISTIC to fit the model.

• Design matrix from PROC LOGISTIC
• Design matrix from PROC GLMSELECT
• How to use the design matrix: See the last section in this article about regression with splines.
