statsmodels.regression.linear_model.RegressionResults.get_prediction#

RegressionResults.get_prediction(exog=None, transform=True, weights=None, row_labels=None, **kwargs)[source]#

Compute prediction results

Parameters:
exogarray_like, optional

The values for which you want to predict. If the model was not fit using a formula, the columns are matched by position and not by name, so a DataFrame must have its columns in the same order as the exog used to fit the model.

transformbool, optional

If the model was fit via a formula, do you want to pass exog through the formula. Default is True. E.g., if you fit a model y ~ log(x1) + log(x2), and transform is True, then you can pass a data structure that contains x1 and x2 in their original form. Otherwise, you’d need to log the data first.

weightsNone or array_like, optional

Weights interpreted as in WLS, used for the variance of the predicted residual.

row_labelsNone or array_like, optional

A list of row labels to use. If not provided, read exog is available.

pred_kwdsdict, optional

Some models can take additional keyword arguments, see the predict method of the model for details.

Returns:
linear_model.PredictionResults

The prediction results instance contains prediction and prediction variance and can on demand calculate confidence intervals and summary tables for the prediction of the mean and of new observations.
