itnumber: Number of regression fixed point cluster iterations

Description Usage Arguments Details Value Author(s) References See Also Examples

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

1
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.
