In flexFitR: Flexible Non-Linear Least Square Model Fitting

Variance-Covariance matrix for an object of class modeler

Description

Extract the variance-covariance matrix for the parameter estimates from an object of class modeler.

Usage

## S3 method for class 'modeler'
vcov(object, id = NULL, ...)

Arguments

object	An object of class modeler, typically the result of calling the modeler() function.
id	An optional unique identifier to filter by a specific group. Default is NULL.
...	Additional parameters for future functionality.

Value

A list of matrices, where each matrix represents the variance-covariance matrix of the estimated parameters for each group or fit.
