Even small probabilities of infection for individuals compound to large probabilities for a large number of people. Carnival needs low risk passengers and screening to be near 100% effective to reduce ...

Robbins (1968) considered the problem of estimating the total probability of the unobserved outcomes of an experiment. In this paper we suggest an estimator, based on n trials, and show that under ...

Statistical estimation techniques involve estimating probability distributions from available data. The fit of data to a particular probability distribution function can be evaluated using various ...

The problem of estimating the variance of the ratio estimator in sampling with probability proportional to aggregate size is investigated. The form of nonnegative unbiased variance estimators is found ...
