vcov {saemix}

Extracts the Variance-Covariance Matrix for a Fitted Model Object

Description

Returns the variance-covariance matrix of the main parameters of a fitted model object

Usage

## S3 method for class 'SaemixRes'
vcov(object, ...)

## S3 method for class 'SaemixObject'
vcov(object, ...)

## S3 method for class 'SaemixObject'
vcov(object, ...)

Arguments

object

a fitted object from a call to saemix

...

further arguments to be passed to or from other methods

Value

A matrix of the estimated covariances between the parameter estimates in model. In saemix, this matrix is obtained as the inverse of the Fisher Information Matrix computed by linearisation
