BLE_SRS: Simple Random Sample BLE

In BayesSampling: Bayes Linear Estimators for Finite Population

Description

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

Usage

BLE_SRS(ys, N, m = NULL, v = NULL, sigma = NULL, n = NULL)

Arguments

ys	vector of sample observations or sample mean (sigma and n parameters will be required in this case).
N	total size of the population.
m	prior mean. If NULL, sample mean will be used (non-informative prior).
v	prior variance of an element from the population (bigger than sigma^2). If NULL, it will tend to infinity (non-informative prior).
sigma	prior estimate of variability (standard deviation) within the population. If NULL, sample variance will be used.
n	sample size. Necessary only if ys represent sample mean (will not be used otherwise).

Value

A list containing the following components:

• est.beta - BLE of Beta (BLE for every individual)

• Vest.beta - Variance associated with the above

• est.mean - BLE for each individual not in the sample

• Vest.mean - Covariance matrix associated with the above

• est.tot - BLE for the total

• Vest.tot - Variance associated with the above
