WebWelcome to Statsmodels’s Documentation. ¶. statsmodels is a Python module that provides classes and functions for the estimation of many different statistical models, as well as for conducting statistical tests, and statistical data exploration. An extensive list of result statistics are available for each estimator. WebReason for it: OLS does not consider, be default, the intercept coefficient and there builds the model without it and Sklearn considers it in building the model. Solution: Add a column of 1's to the dataset and fit the model with OLS and you will get the almost same Rsquared and Adj. Rsquared values for both models.
