P-values from survreg (survival package) using a clusterterm
Hi all.
Belove is the example from the cluster-help page wtih the output.
I simply cannot figure out how to relate the estimate and robust Std. Err to
the p-value. I am aware this a marginal model applying the sandwich
estimator using (here I guess) an emperical (unstructered/exchangeable?)
ICC. Shouldent it be, at least to some extend, comparable to the robust
z-test, for rx :
