PHREG Counting Process Style of Input and binary time-varying covariate.

Hi all,

I have to use counting process approach in survival analysis as one of the vars has >2 groups.

The format is below:

/* Counting Process Style of Input */model (T1,T2) * Status(0) = Treatment X1 X2 X3 X4 (Z1 Z2 Z3) (Y1 Y2 Y3);

X: time time-invarying vars

Z,Y: time-varying vars

And Treatment is binary time-varying covariate.

I am able to merge data of (Z) and (Y) as their (T1,T2) is aligned to each other.

Can you help with the code to merge data (Treatment) and (Z) when their (T1,T2) is not aligned to each other.

Thank you!

Hao
