R: Control the Iterations in monpol

monpol.control

R Documentation

Control the Iterations in monpol

Description

Allow the user to set some characteristics of the monpol monotone polynomial fitting algorithm.

Usage

monpol.control(maxiter = 1000, tol = 1e-05,
               tol1=1e-10, tol2=1e-07, tolqr=1e-07)

Arguments

`maxiter`	A positive integer specifying the maximum number of iterations allowed, used in all algorithms.
`tol`	A positive numeric value specifying an absolute tolerance for determining whether entries in the gradient are zero for algorithms ‘Full’, ‘BCD’, ‘CD1’ and ‘CD2’.
`tol1`	A positive numeric value, used in algorithm ‘Hawkins’. Any number not smaller than `-tol1` is deemed to be non-negative.
`tol2`	A positive numeric value, used in algorithm ‘Hawkins’. Any number whose absolute value is smaller than `tol2` is taken to be zero.
`tolqr`	A positive numeric value, used in algorithm ‘Hawkins’ as tolerance for the QR factorisation of the design matrix.

Value

A list with exactly five components:

`maxiter`
`tol`
`tol1`
`tol2`
`tolqr`

with meanings as explained under ‘Arguments’.
