How to Avoid Trimmed Variable Name

Anybody have any tricks to avoid the output from PROC LOGISTIC,  especially in the "Analysis of Maximum Likelihood Estimates" section.

Sometimes, I have multiple variables such as:

WoE_DV_EST_NUM_TYPE1

WoE_DV_EST_NUM_TYPE2

WoE_DV_EST_NUM_TYPE3

And when one of the variables shows up in this section, I have no idea which one it was! It will trim them off at a certain length

Example of my code: (opening HTML result in Chrome)

ods graphics on;

proc logistic data=TRAINDATA;

model YVAR(event='1') = X1 X2 X3 X4 ...

  / SELECTION = STEPWISE rsq lackfit;

    roc;

  OUTPUT OUT=OUTPUTDATA p=myPrediction ;

run;

ods graphics off;

Re: How to Avoid Trimmed Variable Name

I'm not sure if this is the answer because you haven't posted a picture of your issue but the namelen option may solve your issue.

ods graphics on;

proc logistic data=TRAINDATA NAMELEN=32;

model YVAR(event='1') = X1 X2 X3 X4 ...

  / SELECTION = STEPWISE rsq lackfit;

    roc;

  OUTPUT OUT=OUTPUTDATA p=myPrediction ;

run;

ods graphics off;
