lpl-package {lpl}

Local Partial Likelihood Boostrap test

Description

This package fits a multivariable local partial likelihood model for covariate-biomarker interaction with survival data.

Details

"lpl" is a R package for multivariate covariate-biomarker interaction uisng local partial likelihood method.

Please use the following steps to install 'lpl' package:

1. First, you need to install the 'devtools' package. You can skip this step if you have 'devtools' installed in your R. Invoke R and then type

install.packages("devtools")

2. Load the devtools package.

library(devtools)

3. Install "lpl" package with R commond

install_github("statapps/lpl")

"lpl" uses local partial likelihood to etimate covariate-biomarker interactions and bootstrap method to test the significance of the interactions.
