In tranSurv: Transformation Model Based Estimation of Survival and Regression Under Dependent Truncation and Independent Censoring

#' tranSurv:Transformation Model Based Survival Curve Estimation with Dependent Left Truncation
#'
#' A package that estimates survival curve under a dependent truncation and independent right censoring via a structural transformation method.
#' The package also includes hypothesis test of quasi-independence based on the conditional Kendall's tau of Martin and Betensky (2005) and
#' two versions of the inverse probability weighted Kendall's tau of Austin and Betensky (2014).
