Check if model has converged

Using the return code from the optimizer, check if the code indicates that the optimization converged to a local optimum.

Usage

converged(x, ...)

# S3 method for class 'bgw_mle'
converged(x, ...)

# S3 method for class 'maxLik'
converged(x, ...)

# Default S3 method
converged(x, ...)

Arguments

x

A model object

...

Additional arguments

Value

A logical value indicating if the model has converged

Details

Objects of class bgw_mle are considered converged for the following codes: 3 - X-convergence 4 - Relative function convergence 5 - X- and relative function convergence 6 - Absolute function convergence

Objects of class maxLik are considered converged for the following codes: 0 - Successful convergence (optim based methods, e.g. BFGS) 1 - Gradient close to zero 2 - Successive function values within tolerance limit 8 - Successive function values within relative tolerance limit
