RESUMO

This work has been developed one methodology for the intrablock covariance analysis of partially balanced incomplete block design with p auxiliary variables and two associated classes - PBIB(2). The design parameters were defined according to the symbol notes of BOSE e NAIR (1939). Using the method of least square were obtained: the system of normal equations; the solutions of the parameters effects for practical use in two situations: n1n2; the sum of squares of the parameters being that the sum of squares for treatments, adjusted for blocks and regression was obtained by the method of conditional residue. Numerical example with three auxiliary variables was presented to illustrate the proposed methodology.
