hhh4_W_utils

Extract Neighbourhood Weights from a Fitted hhh4 Model

Description

The getNEweights function extracts the (fitted) weight matrix/array from a "hhh4" object, after scaling and normalization. The coefW function extracts the coefficients of parametric neighbourhood weights from a hhh4 fit (or directly from a corresponding coefficient vector), i.e., coefficients whose names begin with “neweights”.

Usage

getNEweights(object, pars = coefW(object),
             scale = ne$scale, normalize = ne$normalize)
coefW(object)

Arguments

`object`	an object of class `"hhh4"`. `coefW` also works with the coefficient vector.
`pars`	coefficients for parametric neighbourhood weights, such as for models using `W_powerlaw`. Defaults to the corresponding point estimates in `object`.
`scale,normalize`	parameters of the `ne` component of `hhh4`.
