Abstract

scsomersd, sccendif and sccenclope compute confidence intervals for rank statistics comparing scenarios. Scenarios are alternative versions of the data, differing in the values of sampling probability weights and/or in the values of an outcome variable. The scenario-comparison rank statistics compare 2 scenarios, denoted Scenario 0 and Scenario 1, derived from the dataset in the memory, in a temporary extended dataset with 1 observation per original observation per scenario. scsomersd estimates the Somers' D or Kendall tau-a of the outcome variable, and sccendif and sccenslope estimate the Hodges-Lehmann percentile differences of the outcome variable, with respect to scenario membership. Examples of between-scenario rank statistics include the Gini coefficient of inequality, the population attributable risk (PAR), percentiles of weighted and/or clustered samples, and Hodges-Lehmann percentile differences between paired samples. scsomersd, sccendif and sccenclope use the packages somersd and expgen, which must be installed in order for the programs to work, and can be downloaded from SSC.
