BLE_SSRS {BayesSampling}R Documentation

Stratified Simple Random Sample BLE

Description

Creates the Bayes Linear Estimator for the Stratified Simple Random Sampling design (without replacement)

Usage

BLE_SSRS(ys, h, N, m = NULL, v = NULL, sigma = NULL)

Arguments

ys

vector of sample observations or sample mean for each strata (sigma parameter will be required in this case).

h

vector with number of observations in each strata.

N

vector with the total size of each strata.

m

vector with the prior mean of each strata. If NULL, sample mean for each strata will be used (non-informative prior).

v

vector with the prior variance of an element from each strata (bigger than sigma^2 for each strata). If NULL, it will tend to infinity (non-informative prior).

sigma

vector with the prior estimate of variability (standard deviation) within each strata of the population. If NULL, sample variance of each strata will be used.

Value

A list containing the following components:
