This package implemented MORST, a fast and powerful test that is designed to be power-robust to the strength of signals. While mainly motivated from the linear regression setting, MORST is a generic test and has several versions. This package implemented the score version of MORST in GLMs and a specific function of MORST tailored to genetic association studies. At the core of MORST, it is the choice of the ridge-type parameter tau_c, which is implemented in this package. With tau_c, one can easily develop other versions of MORST or adapt MORST to other applications.
In addition, this package also implemented the Burden, SKAT and ACAT-V tests, and the ensemble versions of Burden, SKAT and MORST (e.g., the ensemble Burden test).

If you would like to use MORST that is specific for genetic association analysis, please use the function SetBasedTests
, which also implemented the Burden, SKAT and ACAT-V tests. If you would like to use MORST for other general applications, please use the function MORST_glm
.
If you would like to use the ensemble Burden, SKAT and MORST tests for genetic association analysis, please use the function EnsembleSetTests
.
