Comparison of Models in Cross-Sectional Studies with Binary Response

The GLM model uses for analysis of binary data in cross-sectional studies. Logestic, probit and complemently log-log are models that uses in GLMʹs. The quasi-likelihood method is the other method that usually was used. In this method, we donʹt need to response distributions. Although this method provides consistent estimators for regression coefficient, in this article using simulation and considering sucsses probability conditional an observed value for concomitant variables, we show that quasi-likelihood method gives unusual result, relative to GLMʹ s when the sample size is small. This method compaire with the other method proposed by Aranda Ordaz [2]. Also, various models uses in a applied example.
