  • This article presents a decision making model of collegiate courts based on logistic regression and decision tree methods to project votes of collegiate members. The model is applied at the level of individual votes and generates information about how different influences can affect the votes within the collegiate chambers. The variables identified as significant in the regression model were the Collegiate, type of defendant and President of Brazil. The percentage of success obtained by the decision tree in the test sample was 81.33% and the regression model percentage of success was 65.4%.
