converged: Check model convergence

In latrend: A Framework for Clustering Longitudinal Data

Check model convergence

Description

Check whether the fitted object converged.

Usage

converged(object, ...)

## S4 method for signature 'lcModel'
converged(object, ...)

Arguments

object	The model.
...	Not used.

Value

Either logical indicating convergence, or a numeric status code.

The default lcModel implementation returns NA.

Implementation

Classes extending lcModel can override this method to return a convergence status or code.

setMethod("converged", "lcModelExt", function(object, ...) {
  # return convergence code
})
