All SNPs are jointly associated to the phenotype and at the same time correlation among them is considered. Thus, correction for population structure becomes unnecessary, which in many cases results in a power advantages compared to other methods.

The package can be installed from an R console via devtools
(If you haven't yet installed devtools
please do so first).
# install.packages("devtools")
devtools::install_github("QTCAT/qtcat")
The qtcatQtc
-function example gives an overview of the functionality of
the package and can be accessed once the package is loaded.
library(qtcat)
example(qtcatQtc, run.dontrun = TRUE)
The data used in the example can be found under inst/extdata
