fpc (version 2.1-6)

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.

Value

  • An integer.

Details

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