摘要
Since Bross introduced the method of ridit analysis in 1956, the variance of 0—1 uniformly-distributed variable, 1/12, has been used as the ridit variance in the interval estimations and significance tests. The maximum variance of a ridit has also been obtained. Yet the analytic expression of the ridit variance could not be deduced. Hence, it is difficult, by theoretical means, to prove the equivalent relation between the ridit analysis and some of the similar tests in the nonparametric statistical methods.
