Title: Correlation of Bivariate Survival Times
Author: Meinhard Ploner, Alexandra Kaider and Georg Heinze
Description: Estimates correlation coefficients with associated
for bivariate, partially censored survival times. Uses
the iterative multiple imputation approach proposed
by Schemper, Kaider, Wakounig and Heinze, Statistics
in Medicine 2013. Provides a scatterplot function to visualize the bivariate
distribution, either on the original time scale or as copula.

Description: Various functions for discrete time survival analysis and longitudinal analysis. SIMEX method for correcting for bias for errors-in-variables
in a mixed effects model. Asymptotic mean and variance of different proportional hazards test statistics using different ties methods given two
survival curves and censoring distributions. Score test and Wald test for regression analysis of grouped survival data. Calculation of survival
curves for events defined by the response variable in a mixed effects model crossing a threshold with or without confirmation.
