Methods for estimation of multivariate average hazard ratios as defined by Kalbfleisch and Prentice. The underlying survival functions of the event of interest in each group can be estimated using either the (weighted) Kaplan-Meier estimator or the Aalen-Johansen estimator for the transition probabilities in Markov multi-state models. Right-censored and left-truncated data is supported. Moreover, the difference in restricted mean survival can be estimated.

Fixed variance estimation for restricted mean method rmeanDiff
.
Removed start
parameter from function wkm
(and all functions
passing arguments to wkm
such as ahrWKM
and
rmeanDiff
). Replaced with rr.subset
parameter (logical vector
indicating which rows from the data.frame should be used for
response rate estimation. This is more flexible than before and does
not require wkm
to know about recruitment times.
Test cases are now run automatically when R CMD check
is called.
