statsmodels.regression.linear_model.OLSResults

class statsmodels.regression.linear_model.OLSResults(model, params, normalized_cov_params=None, scale=1.0, cov_type='nonrobust', cov_kwds=None, use_t=None)[source]

Results class for for an OLS model.

Most of the methods and attributes are inherited from RegressionResults. The special methods that are only available for OLS are:

  • get_influence
  • outlier_test
  • el_test
  • conf_int_el
