crrcbcv

A user friendly function 'crrcbcv' to compute bias-corrected variances for competing risks regression models using proportional subdistribution hazards with small-sample clustered data. Four types of bias correction are included: the MD-type bias correction by Mancl and DeRouen (2001) doi:10.1111/j.0006-341X.2001.00126.x, the KC-type bias correction by Kauermann and Carroll (2001) doi:10.1198/016214501753382309, the FG-type bias correction by Fay and Graubard (2001) doi:10.1111/j.0006-341X.2001.01198.x, and the MBN-type bias correction by Morel, Bokossa, and Neerchal (2003) doi:10.1002/bimj.200390021.
