Proc Mianalyze Computing Overall p-value for Supremum Test in Proportional Hazards Assumption

[YYK273]

I'm currently working on testing the overall Proportional Hazards Assumption for my 5 multiple imputation datasets. 

My challenge lies in determining the overall p-value of the Supremum Test for Proportional Hazards Assumption. While the test only provides the Maximum Absolute Value and Pr > MaxAbsVal, I'm uncertain about how to derive the overall p-value from proc mianalyze.

Could you kindly provide some guidance or insights on how to approach this issue? Any assistance or pointers you could offer would be greatly appreciated.

Thank you very much for your time and assistance.

The theory behind combining the multiply imputed estimates requires that there be a point estimate and standard error.  Since the Supremum test only reports the maximum and a p-value, there is no easy way to get combined estimates.
