Horvitz-Thomson Estimator, The
摘要
The Horvitz-Thompson (H-T) estimator is attributed to D. G. Horvitz and D. J. Thompson to estimate a finite population total when a sample is selected with unequal probabilities without replacement. Let U = (1, ⋯ , i, ⋯ , N) denote a finite universe of N elements and s be a sample of size n.
