piktfrompik: pikt from pik

In RJauslin/StratifiedSampling: Different Methods for Stratified Sampling

pikt from pik

Description

This function finds the pikt from an initial pik.

Usage

piktfrompik(pik, max_iter = 500L, tol = 1e-08)

Arguments

pik	A vector of inclusion probabilities. The vector must contains only value that are not integer.
max_iter	An integer that specify the maximum iteration in the Newton-Raphson algorithm. Default 500.
tol	A scalar that specify the tolerance convergence for the Newton-Raphson algorithm. Default 1e-8.

Details

The management of probabilities equal to 0 or 1 is done in the cps function.

pikt is the vector of inclusion probabilities of a Poisson sampling with the right parameter. The vector is found by Newtwon-Raphson algorithm.

More details could be find in Tille (2006).

Value

An updated vector of inclusion probability.
