el2.cen.EMm             Computes p-value for multiple mean-type
                        hypotheses, based on two independent samples
                        that may contain censored data.
el2.cen.EMs             Computes p-value for a single mean-type
                        hypothesis, based on two independent samples
                        that may contain censored data.
el2.test.wtm            Computes maximum-likelihood probability jumps
                        for multiple mean-type hypotheses, based on two
                        independent uncensored samples
