Rollingols python
Webclassmethod RollingOLS.from_formula(formula, data, window, weights=None, subset=None, *args, **kwargs) Create a Model from a formula and dataframe. Parameters: formula str or generic Formula object The formula specifying the model. data array_like The data for the model. See Notes. subset array_like Webrolling_beta = sm.OLS (df ['X2'], df ['X1'], window_type='rolling', window=30).fit () rolling_beta.params Output: X1 -0.075784 dtype: float64 And this at least represents the structure of your output too, meaning that you're expecting an estimate for each of your sample windows, but instead you get a single estimate.

WebRollingOLS.fit(method='inv', cov_type='nonrobust', cov_kwds=None, reset=None, use_t=False, params_only=False) Estimate model parameters. Parameters: method{‘inv’, ‘lstsq’, ‘pinv’} Method to use when computing the the model parameters. ‘inv’ - use moving windows inner-products and matrix inversion. minion buttonsmotels nags head nc pet friendlyWebReason 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.
