PACHECO, MARIO  y  MARTINEZ, GUILLERMO. A Jackknife Variance Estimator under Two-Fases Sampling with Unequal Probability. Rev.Colomb.Estad. [online]. 2007, vol.30, n.2, pp.203-212. ISSN 0120-1751.

We propose a jackknife variance estimator under two-fases sampling with unequal probability. We assume that the parameters of interest and its stimators can be expressed as a function of means. We propose a jackknife estimator for each component of variance. We demonstrate that the estimator is consistent for the same asymptotic variance as the linearization estimator. Also we support this result with a simulation study.
