var_FixedPoint {UPSvarApprox} | R Documentation |
Fixed-Point approximate variance estimator
Description
Fixed-Point estimator for approximate variance estimation by Deville and Tillé (2005). Estimator of class 2, it requires only first-order inclusion probabilities and only for sample units.
Usage
var_FixedPoint(y, pik, maxIter = 1000, eps = 1e-05)
Arguments
y |
numeric vector of sample observations |
pik |
numeric vector of first-order inclusion probabilities for sample units |
maxIter |
a scalar indicating the maximum number of iterations for the fixed-point procedure |
eps |
tolerance value for the convergence of the fixed-point procedure |
Value
a scalar, the estimated variance
