WebbThe Scheirer–Ray–Hare test is a nonparametric test used for a two-way factorial design. It appears to be not well documented, but it is discussed in Sokal and Rohlf (1995).

Webbwhere s 2 (w) is the pooled variance within subjects, and s 2 (b) is the variance of the trait between subjects.. It is easily shown that s 2 (b) + s 2 (w) = the total variance of ratings--i.e., the variance for all ratings, regardless of whether they are for the same subject or not. Hence the interpretation of the ICC as the proportion of total variance accounted for by …
