Hello all,
I am trying to match on 4 year bins around year of diagnosis, it seems like
no matter what cut points I specify (even none) I always get an exact match
on year of diagnosis. It is a numeric variable.
mat4 <- matchit(pc ~ TeachingHospital + sex + ageDx1 + YRDX1 + hrr +
dxtodeath, data=pa, method = "cem", cutpoints = list(ageDx1=8, sex=0,
dxtodeath=dxcut2, TeachingHospital=0, yrdx1=1), keep.all=TRUE)
Thank you,
