The main function is `gLRT`

, in which a method is selected. Depending on the method specified, one of the five functions (`gLRT1`

, `gLRT2`

, `gLRT3`

, `gLRT4`

, `ScoreTest`

) is called to perform a generalized logrank test or a scor test. Before computing the test statistic in each test, function `ModifiedEMICM`

is called to compute an NPMLE of the common survival function under the null hypothesis that all treatments have the same survival function except for in `gLRT4`

, where `ModifiedEMICM`

is used to estimate the survival function of each treatment group.
