lmmvar

An R package for computing test statistics and confidence intervals for a variance component or proportion in a linear mixed model using the method described in Fast and reliable confidence intervals for a variance component or proportion.

This package will be updated sporadically. Please contact yiqiaozhang@ufl.edu with any questions or comments.

Installation

lmmvar can be loaded directly into R through the devtools package:

# install.packages("devtools")
# library(devtools)
# devtools::install_github("yqzhang5972/lmmvar")
