The algorithm implemented in this package was designed to quickly estimates the distribution of the logrank especially for heavy unbalanced groups. VALORATE estimates the null distribution and the pvalue of the logrank test based on a recent formulation. For a given number of alterations that define the size of survival groups, the estimation involves a weighted sum of distributions that are conditional on a cooccurrence term where mutations and events are both present. The estimation of conditional distributions is quite fast allowing the analysis of large datasets in few minutes <http://bioinformatica.mty.itesm.mx/valorate>.
