#### Transformation model for left-truncated right-censored survival data
***tranSurv*** implements methods for survival analysis under a dependent truncation and independent right censoring via a structural transformation method.
The package is still under active development.

---

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).

## Installation

Install and load the package from CRAN using 

```{r install, eval = FALSE}
install.packages("tranSurv")
library(tranSurv)
```

Install and load the package from GitHub using 
```{r github, eval = FALSE}
devtools::install_github("stc04003/tranSurv")
library(tranSurv)
```
