Enquiry about 2nd-order interactions survival analysis
...ted email. I know about Dr Terry
> through R package "survival" and alot of your papers.
>
> As we know Equation(1) is a normal parametric survival analysis, I'ld
> like to modify it to be a 2nd-order interactions as in Equation(2) :-
> h(t|X=x) = exp(Beta0 + XBeta1) ------- (1)
> h(t|(X=x,Z=z)) = exp(Beta0 + XZBeta1) ------ (2)
>
> Where x and z are two covariates:
> x = dummy variable (1 or 0)
> z = factors (people name)
>
> I would like to modify survreg() to be a second-order interactions
> regression while there is no 2nd-orde...
