Version 3.1.3 (updated May 15, 2021)

This package includes tostt and tostti which perform t tests of mean equivalence, tostpr and tostpri which perform z tests of proportion equivalence, tostmcc and tostmcci which perform equivalence McNemar's tests, the tostranksum and tostsignrank which perform equivalence tests based on the z approximation to the rank sum and sign rank testsi, and the tostrrp and tostrrpi commands which perform tests for equivalence of relative risk and unity in paired binary data. All tests have the option to report relevance test conclusions.

This package is written for Stata versions 8+.
