vcov.bbreg {bbreg}

vcov.bbreg

Description

Function to extract the variance-covariance matrix of the parameters of the fitted regression model (bessel or beta).

Usage

## S3 method for class 'bbreg'
vcov(object, parameters = c("all", "mean", "precision"), ...)

Arguments

object

an object of class "bbreg" containing results from the fitted model.

parameters

a string to determine which coefficients should be extracted: 'all' extracts all coefficients, 'mean' extracts the coefficients of the mean parameters and 'precision' extracts coefficients of the precision parameters.

...
