which calculate confidence intervals for a range of parameters behind rank or "nonparametric" statistics. somersd calculates confidence intervals for generalized Kendall's tau-a or Somers' D parameters,

It can be used on left-censored, right-censored, clustered and/or

or Kendall's tau-a estimated. cendif is an easy-to-use program to calculate confidence intervals for Hodges-Lehmann median differences

can be used to calculate confidence intervals for a wide range of rank-based parameters, which are special cases of Kendall's tau-a, Somers' D or percentile slopes. These parameters include differences

ROC areas, Gini coefficients, population attributable risks, median differences, ratios, slopes and per-unit ratios, and the parameters behind the sign test and the Wilcoxon-Mann-Whitney or Breslow-Gehan
