mboost vs gbm
I'm attempting to fit boosted regression trees to a censored response using
IPCW weighting. I've implemented this through two libraries, mboost and
gbm, which I believe should yield models that would perform comparably.
This, however, is not the case - mboost performs much better. This seems
odd. This issue is meaningful since the output of this regression needs to

Software/algorithms for competing risks analysis
...ming the following types of competing risks analyses:
(1) cumulative (crude) incidence regression
(2) Gray's K-sample log-rank test for cmulative incidence
(3) multi-state models
(4) dependent competing risks modeling with (a) copulas, (b) Robin's
Inverse probability of censoring weighted (IPCW) estimator, (c) frailty
I would really appreciate any pointers/references to
algorithms/software in other environments such as SAS/STATA/SPSS, as
well as in R.
Thanks very much,
Ravi.
