# Goodness of fit for surveylogistic

Hi,

I actually wanted testing the goodness of fit of my model developed from PROC SURVEYLOGISTIC but since it doesn't give such options, I opted for PROC LOGISTIC just to test the goodness of fit of my model it gave me the output below. can I say my model is adequate?

SAS Output

Do you have 57.000 degrees of freedom in your model?

``````PROC LOGISTIC DATA= risk ;
CLASS X1 X2 X3 X5 X6 X7 X8 X9 X10 X13 X14 X15 X16 X17/param=glm;
MODEL Y (Event = '1')=X1 X2 X3 X4  X5 X6 X7 X8 X9 X10 X11 X12 X13 X14 X15 X16 X17/
LINK=LOGIT expb LACKFIT scale=none
aggregate=(X1 X2 X3 X4  X5 X6 X7 X8 X9 X10 X11 X12 X13 X14 X15 X16 X17) ;

If your model looks good, Value/DF should be near 1 .
