R: Updating of MLE fits by profiling

updatesad {sads} | R Documentation

## Updating of MLE fits by profiling

### Description

These functions update a fitsad/fitrad object by running the optimizer again starting on better fit returned by profile.

These functions were not extensively tested, and should be considered in beta testing phase.

### Usage

    updatesad(object, ...)
    updaterad(object, ...)

### Arguments

`object` | object of the class `fitsad-class` or `fitrad-class` for which the optimization did not converge, or converged to a local minimum.
`...` | list of additional parameters to be passed to the `fitsad` or `fitrad` fitting procedure. May include a different optimizer, method, or upper/lower bounds for the parameters. Refer to the `fitsad` and `fitrad` man pages for details of which parameters may be specified.

### Details

The `updatesad` function runs a new profile of the fitted object, and if the profile is able to find a better fit, it runs a new optimization starting on this better fit. If the profiling does not find a new fit, the function exits with error. The actual processing is done by `updatesad`. `updaterad` is simply a convenience alias.

### Value

An object of `fitsad-class` or `fitrad-class`.
