Conteúdo: | In a paper (1938a) on "The statistical utilization of multiple measurements"  the author considered the general procedure of the establishment of discriminant functions, or sets of scores, based on an analysis for covariance, for a bactery of different experimental determinations. In general, these functions are those giving stationary to the ratio of apportionment of sums of squares between n, chosen and n2 residual degrees of freedom. In the simplest application  n1 is unity, and, as was first shown by Hotelling, the primary test of measurements available are effective in making any significant discrimation, is exactly reducible to a simple analysis of variane in which p-1 degrees of freedom (for p variates) are transferred from the residual. In the general case the underlying problem of distribuition has also now been solved(Fisher, 1939).
