crrcbcv:Bias-Corrected Variance for Competing Risks Regression with
Clustered Data
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>.
