This paper describes a procedure for the estimation of fixed and random parameters in multilevel model for proportions. The estimation procedure is developed using Iterative Generalized Least Squares. Once the model is formulated, we demonstrate that it is possible to apply the asymptotic estimation theory in the framework of the general lineal model. An algorithm to calculate the proposed estimators is elaborated. We illustrate the application using an example of meta-analysis. It is concluded that the proposed procedure can be favorable strategy to do applied research.
