Thanks to Kit Baum, a new semi-version of the -somersd- package
(described as below on my website) is now available for download on SSC.
In Stata, use the SSC command to do this. The new semi-version has the
same programs as before, but the manuals -censlope.pdf- and -cendif.pdf-
have been proof-read and updated, removing a few typos and imperfect
notations.

Best wishes

Roger

TITLE
      somersd: Kendall's tau-a, Somers' D and percentile slopes

DESCRIPTION/AUTHOR(S)
      The somersd package contains the programs somersd, censlope and
cendif,
      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,
      and stores the estimates and their covariance matrix as estimation
results.
      It can be used on left-censored, right-censored, clustered and/or
      stratified data. censlope is an extended version of somersd, which
also
      calculates confidence limits for the generalized Theil-Sen median
slopes
      (or other percentile slopes) corresponding to the version of
Somers' D
      or Kendall's tau-a estimated. cendif is an easy-to-use program to
      calculate confidence intervals for Hodges-Lehmann median
differences
      (or other percentile differences) between two groups. The somersd
package
      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
      between proportions, Harrell's c index, areas under receiver
operating
      characteristic (ROC) curves, differences between Harrell's c
indices or
      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
      ranksum tests. Full documentation of the programs (including
methods and
      formulas) can be found in the manual files somersd.pdf,
censlope.pdf and
      cendif.pdf, which can be viewed using the Adobe Acrobat Reader.
