Linear Regression Python Packages

aplr

APLR builds predictive, interpretable regression and classification models using Automatic Piecewise Linear Regression. It often rivals tree-based methods in predictive accuracy while offering smoother and interpretable predictions.

piecewise-regression

piecewise-regression (aka segmented regression) in python. For fitting straight line models to data with one or more breakpoints where the gradient changes.

abess

Fast Best-Subset Selection Library

mlr

Multiple linear regression with statistical inference, residual analysis, direct CSV loading, and other features

mcpower

Simple Monte Carlo statistical power analysis for complex models. Find the sample size you need or check if your study has enough power - even with complex models that traditional power analysis can't handle. (pip install mcpower)
