GNU R analysis of multivariate event times

 Implementation of various statistical models for multivariate
 event history data <doi:10.1007/s10985-013-9244-x>. Including multivariate
 cumulative incidence models <doi:10.1002/sim.6016>, and bivariate random
 effects probit models (Liability models) <doi:10.1016/j.csda.2015.01.014>.
 Also contains two-stage binomial modelling that can do pairwise odds-ratio
 dependence modelling based marginal logistic regression models. This is an
 alternative to the alternating logistic regression approach (ALR).
