rrvglm.optim.control: Control Function for rrvglm() Calling optim()

Description

Algorithmic constants and parameters for running optim within rrvglm are set using this function.

Usage

rrvglm.optim.control(Fnscale = 1, Maxit = 100,
                     Switch.optimizer = 3, Abstol = -Inf,
                     Reltol = sqrt(.Machine$double.eps), ...)

Value

A list with components equal to the arguments.

Arguments

Fnscale

Passed into optim as fnscale.

Maxit

Passed into optim as maxit.

Switch.optimizer

Iteration number when the "Nelder-Mead" method of optim is switched to the quasi-Newton "BFGS" method. Assigning Switch.optimizer a negative number means always BFGS, while assigning Switch.optimizer a value greater than maxits means always use Nelder-Mead.

Abstol

Passed into optim as abstol.

Reltol

Passed into optim as reltol.

...

Ignored.
