marginalize_augmented_model

marginalize_augmented_model(augmented: NxMixedGraph, augmentation_variable: str | QVariable, marginal_parents: Collection[str | QVariable]) → NxMixedGraph

Marginalize out a given collection of variables from an augmented model.

Parameters:

• augmented – NxMixedGraph of the input augmented model

• augmentation_variable – the variable that was previously augmented into the model

• marginal_parents – collection of parents of the augmentation variable to be marginalized out.

Returns:

NxMixedGraph of the marginalized model

Raises:

• ValueError – augmentation_variable must be in the augmented model

• ValueError – marginal_parents cannot be all the parents of augmentation_variable

• ValueError – augmentation_variable must be the only child of the each marginal parent
