case-cohort sampling
Hi.
I've a dataframe with about 46000 women with about 500 cases (cancers). I
want to define a case-cohort sampling scheme, matching by age and hospital
centre. Is there anyone who has already written a code for that? It should
be something similar to the stcacoh macro in Stata.
TIA,
Stefano
