Extract the model weights

weights is a generic function which extracts fitting weights from objects returned by modeling functions. Methods can make use of napredict methods to compensate for the omission of missing values. The default methods does so.

# S3 method for class 'cpglm'
weights(object, type = c("prior", "working"), ...)

# S3 method for class 'hierCredGLM'
weights(object, type = c("prior", "working"), ...)

# S3 method for class 'hierCredTweedie'
weights(object, type = c("prior", "working"), ...)

Arguments

object

an object for which the extraction of model weights is meaningful. Can be either cpglm, glm, hierCredibility, hierCredGLM or hierCredTweedie

type

indicates if prior or working weights need to be extracted.

...

ignored

Value

Weights extracted from the object object: the default method looks for component "weights" and if not NULL calls napredict on it.
