var_HartleyRao {UPSvarApprox} | R Documentation |
Hartley and Rao approximate variance estimator
Description
Compute the an approximate variance estimator obtained by the approximation of joint-inclusion probabilities proposed by Hartley and Rao (1962). Estimator of class 3, it requires only first-order inclusion probabilities but for all population units.
Usage
var_HartleyRao(y, pik, sample)
Arguments
y |
numeric vector of sample observations |
pik |
numeric vector of first-order inclusion probabilities for all population units |
sample |
Either a numeric vector of length equal to the sample size with
the indices of sample units, or a boolean vector of the same length of |
Value
a scalar, the estimated variance
