icfitControl {interval}

Auxiliary for controling icfit

Description

A function to create a list of arguments for icfit.

Usage

icfitControl(epsilon = 1e-06, maxit = 10000, initfitOpts=NULL, conf.level=.95, B=200, 
    confMethod="modboot",seed=19439101, timeEpsilon=1e-06, timeMessage=TRUE) 

Arguments

epsilon

The minimum error for convergence purposes. The EM algorithm stops when error < epsilon, where error is the maximum of the reduced gradients (see Gentleman and Geyer, 1994)

maxit

maximum number of iterations of the EM algorithm

initfitOpts

named list of options for initfit function if initfit is function name

conf.level

level for confidence interval, used if conf.int=TRUE

B

number of bootstrap replications for conf.int=TRUE, must be at least 11

confMethod

method for confidence intervals, must be "modboot"

seed

random seed for bootstrap, if NULL no call to set.seed

timeEpsilon

small number for adding or subtracting from time for drawing confidence interval lines

timeMessage

logical, print estimate of how long modified bootstrap confidence intervals will take to calculate?

Details

There is only one option for the confMethod now. The confMethod argument is only needed for future versions if there is another confidence interval method option. For a description of the modified bootstrap method see icfit.

Value

An list with the arguments as components.
