The logistic regression classification algorithm with LASSO (L1) or ridge (L2) regularization.
Data: input dataset
Preprocessor: preprocessing method(s)
Learner: logistic regression learning algorithm
Model: trained model
Coefficients: logistic regression coefficients
Logistic Regression learns a Logistic Regression model from the data. It only works for classification tasks.
A name under which the learner appears in other widgets. The default name is “Logistic Regression”.

The widget is used just as any other widget for inducing a classifier. This is an example demonstrating prediction results with logistic regression on the hayes-roth dataset. We first load hayes-roth_learn in the File widget and pass the data to Logistic Regression. Then we pass the trained model to Predictions.
Now we want to predict class value on a new dataset. We load hayes-roth_test in the second File widget and connect it to Predictions. We can now observe class values predicted with Logistic Regression directly in Predictions.
