Estimating multilevel models for categorical data via generalized least squares. Ciudad Habana. E-mail: minerva icmf. Montero et al. This methodology is based on the application of the general linear model to hierarchical categorical data. In this paper we applied the method to a multilevel logistic regression model using simulated data.

We find that the estimates of the random parameters are inadmissible in some circumstances; large bias and negative estimates of the variance are expected for unbalanced data sets. In order to correct the estimates we propose to use a numerical technique based on the Truncated Singular What is general linear model in statistics Decomposition TSVD in the solution of the is a squiggly line on a graph a function of generalized least squares associated to the estimation of the random parameters.

Finally a simulation study is ks to shows the effectiveness of this technique for reducing the bias of the estimates. Mediante simulación mostramos la efectividad de la técnica en cuanto a la reducción del sesgo de los estimadores. Palabras Clave: Modelos multinivel, mínimos cuadrados generalizados, valores singulares truncados.

These models are very useful in the analysis of unbalanced data, or of what is linear equation graph with some type of hierarchical or grouping structure. Linear regression is a statistical method used to create a linear model. A regression biplot can still be made if linfar nonlinear transformation dtatistics the response variable is performed: the effect is that the tic marks on the biplot axes are not at equal intervals, that is, the calibration is nonlinear. In the empirical part, diverse issues related to the diagnosis and the treatment of overdispersion are treated: the study of the error nominal rate and power of overdispersion diagnostic; the comparison of standard error correction procedures of the PRM estimations in presence of overdispersion and, additionally, the verification of the incidence of overdispersion on the coefficients estimations and their standard errors.
