Cox–Mantel test

Statistics

A non-parametric test for comparing two survival curves (see hazard rate), which results from the work of Sir David Cox and Nathan Mantel. Denote the total number of deaths in the second group by D₂, and let the ordered survival times of the combined group be t₍₁₎<t₍₂₎<⋯<t_(k). The test statistic, C, is given by C = U/, where $Cox–Mantel test$ and m_(j) is the number of survival times equal to t_(j), d_(j) is the total number of individuals who died (or were censored) at time t_(j), and p_(j) is the proportion of these who were in the second group. If the differences between the survival curves are attributable to random variation then C has a standard normal distribution.
