Computes the Tau squared index of "effect magnitude". The maximization of this criterion is equivalent to the minimization of Wilk's lambda statistic.
WebThe index \tau^2 τ 2 is related to the Wilk's lambda statistic ( \Lambda Λ) by: \tau^2 = 1 - \lambda^ { (1/r)} τ 2 = 1−λ(1/r) where r r is the rank of H H the Effect matrix.
