It is the best suited type of regression for cases where we have a categorical dependent variable which can take only discrete values. sklearn.metrics.classification_report¶ sklearn.metrics.classification_report (y_true, y_pred, *, labels=None, target_names=None, sample_weight=None, digits=2, output_dict=False, zero_division='warn') [source] ¶ Build a text report showing the main classification metrics. To train our model, we will first need to import the appropriate model from scikit-learn with the following command: Prerequisite: Understanding Logistic Regression Logistic regression is the type of regression analysis used to find the probability of a certain event occurring.
