statsmodels.genmod.generalized_linear_model.PredictionResultsMean.conf_int¶
- PredictionResultsMean.conf_int(method='endpoint', alpha=0.05, **kwds)[source]¶
Confidence interval for the predicted value.
This is currently only available for t and z tests.
- Parameters:
method ({"endpoint", "delta"}) – Method for confidence interval, “m If method is “endpoint”, then the confidence interval of the linear predictor is transformed by the prediction function. If method is “delta”, then the delta-method is used. The confidence interval in this case might reach outside the range of the prediction, for example probabilities larger than one or smaller than zero.
alpha (float, optional) – The significance level for the confidence interval. ie., The default alpha = .05 returns a 95% confidence interval.
kwds (extra keyword arguments) – currently ignored, only for compatibility, consistent signature
- Returns:
ci – The array has the lower and the upper limit of the confidence interval in the columns.
- Return type:
ndarray, (k_constraints, 2)
