Linear rank test statistics are applied to the problem of estimating a treatment effect if two sets of censored failure time data are compared and the distributions of the log‐failure times of the two samples are assumed to differ only in location. Rank tests for this accelerated failure time model are reviewed and Hodges‐Lehmann type estimates for the shift parameter are proposed. Properties of these estimates are investigated, computational aspects are discussed and an example is presented.
