This paper present the process of simplication of the function maximum likelihood gradient, used in the estimation of conrmatory factor analysis. The gradient obtained is presented infunction of CFA tradition al matrix: Λ, Φ y Θe (regression coefcients, variances of latent variables and error variances). This simplication was performed using matrices derivation laws and yielded an expression for the gradient easy for programing.
