In [[statistics]], the '''Horvitz–Thompson estimator''', named after Daniel G. Horvitz and Donovan J. Thompson,<ref>Horvitz,D. G.; Thompson, D. J. (1952) "A generalization of sampling without replacement from a finite universe", ''[[Journal of the American Statistical Association]]'', 47, 663–685, . {{jstor\|2280784}}</ref> is a method for estimating the total<ref>William G. Cochran (1977), ''Sampling Techniques'', 3rd Edition, Wiley. ISBN 0-471-16240-X</ref> and mean of a [[Sampling (statistics)\|superpopulation]] in a [[stratified sample]]. [[Inverse probability weighting]] is applied to account for different proportions of observations within strata in a target population. The Horvitz–Thompson estimator is frequently applied in [[Statistical survey\|survey analyses]] and can be used to account for [[missing values\|missing data]].

			==The method==
			Formally, let <math>Y_i, i = 1, 2, \ldots, n</math> be an [[independence (probability theory)\|independent]] sample from ''n'' of ''N ≥ n'' distinct strata with a common mean ''μ''. Suppose further that <math>\pi_i</math> is the [[inclusion probability]] that a randomly sampled individual in a superpopulation belongs to the ''i''th stratum. The Horvitz–Thompson estimate of the total is given by:
			: <math>
			\hat{Y}_{HT} = \sum_{i=1}^n \pi_i ^{-1} Y_i,
			</math>

			and the estimate of the mean is given by:
			: <math>
			\hat{\mu}_{HT} = N^{-1}\hat{Y}_{HT} = N^{-1}\sum_{i=1}^n \pi_i ^{-1} Y_i.
			</math>

			In a [[Bayesian probability\|Bayesian]] probabilistic framework <math>\pi_i</math> is considered the proportion of individuals in a target population belonging to the ''i''th stratum. Hence, <math>\pi_i^{-1} Y_i</math> could be thought of as an estimate of the complete sample of persons within the ''i''th stratum. The Horvitz–Thompson estimator can also be expressed as the limit of a weighted [[bootstrapping (statistics)\|bootstrap]] [[resampling (statistics)\|resampling]] estimate of the mean. It can also be viewed as a special case of multiple [[imputation (statistics)\|imputation]] approaches.<ref>Roderick J.A. Little, Donald B. Rubin (2002) ''Statistical Analysis With Missing Data'', 2nd ed., Wiley. ISBN 0-471-18386-5</ref>

			For [[Statistical benchmarking\|post-stratified]] study designs, estimation of <math>\pi</math> and <math>\mu</math> are done in distinct steps. In such cases, computating the variance of <math>\hat{\mu}_{HT}</math> is not straightforward. Resampling techniques such as the bootstrap or the jackknife can be applied to gain consistent estimates of the variance of the Horvitz–Thompson estimator{{Citation needed\|date=July 2013}}. The Survey package for [[R (programming language)\|R]] conducts analyses for post-stratified data using the Horvitz–Thompson estimator.
