Conteúdo: | In a multivariate growth-curve model, the estimator of the parameter matrix is a function of the matrix of the sums of sqaures and of the crossproducts due to error. However, if the assumption of a patterned covariance matrix is valid, then the parasmeter estimator does not depend on the error matrix. A likelihood ratio test of this patterned covariance matrix is constructed anmd its distribution is discussed. A numerical example is provided in which the design consists of two treatments groups, with three repeated measures being taken of the three response variables.
