This paper considers the problem of screening k multivariate normal populat
ions (secondary data) with respect to a control population (primary data) i
n terms of covariance structure. A screening procedure, developed based upo
n statistical ranking and selection theory, is designed to include in the s
elected subset those populations which have the same (or similar) covarianc
e structure as the control population, and exclude those populations which
differ significantly. Formulas for computing the probability of a correct s
election and the least favorable configuration are developed. The sample si
ze required to achieve a specific probability requirement is also developed
, with results presented in tabular form. This secondary data selection pro
cedure is illustrated via an example with applications to radar signal proc
essing. (C) 1999 Academic Press.
