Thank you Dr. David.
I try to summarize it.
Assumes x and z are two covariates:
x = dummy variable (1 or 0)
z = factors (people name)
x*z = x + z + x*z
Actually I said = x + z + x:z
And interaction formula of a two level dummy with a multi-level
Thank you Dr. David.

therefore this is not a 2nd-order interactions, it should be (for an
exponential survival regression):-
h(t|(X=x,Z=z)) = exp(Beta0 + XZBeta1)

As we know a normal survival regression is the equation (1)
Well, I'ld like to modify it to

Well, I'ld like to modify it to be 2nd-order interaction model as shown in
