maxLik (version 1.4-6)

nIter: 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, …)
# S3 method for default
nIter(x, …)

Arguments

x

a statistical model, or a result of maximisation, created by maxLik, maxNR or another optimizer.

further arguments for methods

Value

numeric, number of iterations. Note that ‘iteration’ may mean different things for different optimizers.

Details

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

Examples

Run this code
# NOT RUN {
## Estimate the exponential distribution parameter:
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)
# }
