itnumber

Number of regression fixed point cluster iterations

Description

Computes the number of fixed point iterations needed by fixreg to find mtf times a fixed point cluster (FPC) of size cn with an approximated probability of prob.

Thought for use within fixreg.

Usage

itnumber(n, p, cn, mtf, prob = 0.95, maxir = 20000)

Arguments

`n`	positive integer. Total number of points.
`p`	positive integer. Number of independent variables.
`cn`	positive integer smaller or equal to `n`. Size of the FPC.
`mtf`	positive integer.
`prob`	number between 0 and 1.
`maxir`	positive integer. `itnumber` is set to this value if it would otherwise be larger.

Details

The computation is based on the binomial distribution with probability given by clusexpect with ir=1.

Value

An integer.
