If you conduct simple random sampling with replacement, choosing n objects from a population of N, then the number K of sampled items has a classical occupancy distribution with probability mass function: P ( K = k N, n) = ( N) k ⋅ S ( n, k) … Web3.1 Drawing a SRSWOR.

Webp θ = p θ srswor θ′ (2.2) where θˆ′ is the usual form of estimator for θ under srswor, which is normally different from θˆ.For example, to estimate the population mean, one may use the ratio mean θˆ = s w i y i / s w i with sampling weights w i but θˆ′ would be the sample mean s y i /n. We will see the effect of a particular ...
