如何通过 R 在 IPTW（治疗加权的逆概率）队列中实施竞争风险分析

Question

Because the baseline characters of two group were different, IPTW were used to balance the two groups, and it has been done in R. "cmprsk" package in R were used to get cumulative incidence curves (CIFs) for competing risk. I know how to get a non-weigted CIF in the crude cohort, however, I don't know how to creat a weighted CIF in IPTW cohort. In previous reports, we have noticed this function can be implemented by SAS or Stata, but we don't have the access to the two software, so how to implement Inverse probability of treatment-weighted competing risks analysis in R is very important for me.

R 的 cmprskcoxmsm 包确实实现了 IPTW 竞争风险分析https://cran.r-project.org/web/packages/cmprskcoxmsm/cmprskcoxmsm.pdf
