WebThe Linear Regression model is fitted using the LinearRegression() function. Ridge Regression and Lasso Regression are fitted using the Ridge() and Lasso() functions respectively. For the PCR model, the data is first scaled using the scale() function, before the Principal Component Analysis (PCA) is used to transform the data. WebGenerally, logistic regression in Python has a straightforward and user-friendly implementation. It usually consists of these steps: Import packages, functions, and classes. Get data to work with and, if appropriate, transform it. Create a classification model and train (or fit) it with existing data.
