“…Bartlett and Please [2], under the assumption of the uniform covariance structure given in (1.12) where all parameters are assumed to be known, estimated an upper bound for the TPMC; Marco et al [10], working with the same uniform covariance structure assumption, but with all the parameters unknown, obtained an asymptotic estimate of the TPMC; Young et al [21], with no covariance restrictions but with all parameters are assumed known, estimated an upper bound for the TPMC; all these authors utilized an analog of Q 2 . We also applied the asymptotic approximations of Okamoto [16] Recall that we modified Stocks' data set, reducing the number of variables from ten to seven, because the biplot in Fig.…”
