Thanks Wensui and Andrew,
I am not specifically assessing survival, rather a predictor of
survival.
New code:
proc logistic data=newhl;
model shfm1=out_365/ lackfit;
run;
At the bottom of the output, I see:
Association of Predicted Probabilities and Observed
Responses
Percent Concordant 24.5 Somers' D
0.170
Percent Discordant 7.5 Gamma
0.531
Percent Tied 68.0 Tau-
a 0.70
Pairs 95266
c 0.585
I do not see the 'c-statistic' in this list of associations, which
makes me think that I am not performing the analysis correctly.
However, other model-fit tests appear here indicating a lackfit-type
of procedure is being performed.
