The aim of this paper consists in an empirical analysis of the effects of heteroscedasticity in the Logit model. The analysis is realized for the data concerning the industrial conjuncture balances in Romania, representing the dependent variable, and some macroeconomic indicators which influence the balances, representing the independent variables. Previously to the identification of the Logit model, the existence of causality between the macroeconomic indicators and the conjuncture balances in industry is tested. The Logit model is estimated for the identified factors, with and without the specification of the heteroscedasticity errors. The heteroscedasticity hypothesis is relaxed with the specification of the functional form of the errors dispersion in the initial regression model. These transformations determine changes of the values of the regression coefficients and the improvement of the indicators adjustment results.
