syst.intercorr {samplingR}

Stratified correlation coefficient

Description

Stratified correlation coefficient

Usage

syst.intercorr(N, n, data)

Arguments

N

Population size

n

Sample size

data

Population data

Details

This value serves as a comparison between systematic and stratified sampling precision.
At value=1 the systematic precision is minimum. At value=0 both sampling methods precision are equal. At value= \frac{-1}{n-1} systematic precision is maximum.
Summarising at values between 1 and 0 stratified sampling estimation has more precision than systematic, so method="strata" should be set at syst.estimator. The other way method="syst" of interpenetrating samples method is better.
