WebMarginal effects provide a way to get results on the response scale, which can aid interpretation. A common type of marginal effect is an average marginal effect (AME). To calculate an AME numerically, we can get predicted probabilities from a model for every observation in the dataset. WebOct 8, 2024 · Binary Logistic Regression Estimates. The model is fitted using the Maximum Likelihood Estimation (MLE) method. The pseudo-R-squared value is 0.4893 which is overall good. The Log-Likelihood difference between the null model (intercept model) and the fitted model shows significant improvement (Log-Likelihood ratio test).
