En este artículo se lleva a cabo la estimación de parámetros y se obtienen diferentes sumas de cuadrados ajustadas para diseños balanceados, en medidas repetidas, con información incompleta a través de tres procedimientos: el método de análisis de varianza de Bartlett; un método multivariado con base en los datos completos y finalmente un método multivariado alterno usando toda la información disponible en el arreglo experimental. Con los tres procedimientos anteriores se llevan a cabo aplicaciones numéricas.
In this paper the estimation of parameters and the different adjusted sums of squares for balanced designs in repeated measures with incomplete information is done through three procedures: the Bartlett's method of covariance analysis; a multivariate method with complete data, and finally, an alternative multivariate method using the available information in the experimental arrangements. Numerical applications using the above procedures are done.
