# TVQRLB: Censored Quantile Regression Model with Time-Varying Covariates under Length-Biased Sampling

The __TVQRLB__ package implements the estimation and inference procedure for the censored quantile regression model which is based on an estimating equation, with time-varying covariates under length-biased sampling scheme.

## Installation

You can install the released version of TVQRLB from GitHub with:

```{r install_github, eval = FALSE}
devtools::install_github("ZexiCAI/TVQRLB")
library(TVQRLB)
```

## Example

This is a basic example with some simulation data:

```{r example}
library(survival)
library(TVQRLB)
TVQRLB(fixedCP.cen20, c(-1, 0.5, 1.5), 100, 0.5)
TVQRLB_OP(fixedCP.cen20, c(-1, 0.5, 1.5), 100, 0.5, 10000)
```
