## Abstract

power pairedproportions p12 p21, power(numlist) discordopts Specify marginal proportions power pairedproportions p1+ p+1, corr(numlist) power(numlist) margopts Compute power Specify discordant proportions power pairedproportions p12 p21, n(numlist) discordopts Specify marginal proportions power pairedproportions p1+ p+1, corr(numlist) n(numlist) margopts Compute effect size and target discordant proportions power pairedproportions, n(numlist) power(numlist) prdiscordant(numlist)[ discordopts where p12 is the probability of a success at occasion 1 and a failure at occasion 2, and p21 is the probability of a failure at occasion 1 and a success at occasion 2. Each represents the probability of a discordant pair. p1+ is the marginal probability of a success for occasion 1, and p+1 is the marginal probability of a success for occasion 2. Each may be specified either as one number or as a list of values in parentheses; see [U] 11.1.8 numlist. 1 2 power pairedproportions — Power analysis for a two-sample paired-proportions tes
