utils.unifend

utils.unifend(model, y=None)

Calculate the endpoints of the uniform residual distributions.

For each observation, this function computes the lower and upper bounds of the predicted cumulative distribution function, P(Y < y) and P(Y <= y).

Parameters

Name	Type	Description	Default
model	object	A fitted model object from the statsmodels library.	required
y	np.ndarray	The observed response variable. If not provided, it will be extracted from the model object.	None

Returns

Name	Type	Description
	np.ndarray	An (n x 2) array where n is the number of observations. Each row contains the [lower, upper] endpoint for a residual’s uniform distribution.

Raises

Name	Type	Description
	ValueError	If the model type is not a recognized statsmodels model.
