nIter {maxLik}R Documentation

Return number of iterations for iterative models

Description

Returns the number of iterations for iterative models. The default method assumes presence of a component iterations in x.

Usage

nIter(x, ...)
## Default S3 method:
nIter(x, ...)

Arguments

x

a statistical model, or a result of maximisation, such as created by maxLik or maxNR

...

further arguments for methods

Details

This is a generic function. The default method returns the component x$iterations.

Value

numeric, number of iterations

Examples

## ML estimation of exponential duration model:
t <- rexp(100, 2)
loglik <- function(theta) sum(log(theta) - theta*t)
## Estimate with numeric gradient and numeric Hessian
a <- maxNR(loglik, start=1)
nIter(a)
