Test for multiple contrasts?
Hello,
I've fitted a parametric survival model by
> survreg(Surv(Week, Cens) ~ C(Treatment, srmod.contr),
> data = poll.surv.wo3)
where srmod.contr is the following matrix of contrasts:
prep auto poll self home
[1,] 1 1 1.0000000 0.0 0
[2,] -1 0 0.0000000 0.0 0
[3,] 0 -1 0.0000000 0.0 0
[4,] 0 0 -0.3333333 1.0 0
[5,] 0 0
