NORMALRIR: Stata module to calculate ridits of inverse ridits between Normal populations

Statistical Software Components from Boston College Department of Economics

Abstract: normalrir inputs expressions to deliver, respectively, a uniform deviate variable, 2 means for 2 Normal populations (Population 1 and Population 0), and 2 standard deviations for the same 2 Normal populations. It outputs a new variable, containing, in each observation, the ridit with respect to Population 0 of a value sampled from Population 1, whose Normal cumulative distribution function for Population 1 has the value of the uniform deviate variable in the same observation. normalrir can be used with the SSC packages expgen and powercal to perform multi-scenario power and sample size calculations for the 2-sample rank statistics Somers' D and Harrell's c, assuming that there exists an unspecified transformation that transforms the outcome variable to a variable with a Normal distribution in each of the 2 populations from which the 2 samples are sampled.
