el2.cen.EMm             Computes empirical likelihood ratio and p-value
                        for multiple mean-type hypotheses, based on two
                        independent samples that may contain censored
                        data.
el2.cen.EMs             Computes empirical likelihood ratio and 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
