title: Simplified computation of the multivariate permutation test for arbitrarily censored survival data.
abstract: This paper points out that the permutational covariance matrix of the multivariate generalization of Gehan's test on censored survival data enjoys the useful property that a generalized inverse may be explicitly computed. This leads to an exceedingly simple formula for the test statistic. The ease of the resulting calculations is displayed with a brief example from exercise stress testing.
