5. estimator
   A prescription for obtaining an estimate from a random sample of data. An estimator is a procedure, not a result, and therefore is a random variable and has a variance. For instance an estimator of the mean weight in adult men may consist of the prescription 'Add up the weights of 100 men and divide...

6. estimator
   A function of data that produces an estimate for an unknown parameter of the distribution that produced the data. The way estimators are often discussed, they can be thought of as chosen before the data are seen. This can be hard to understand for the person new to the term. Properties of estimators...

11. estimator
    An estimator is a rule for `guessing` the value of a population parameter based on a random sample from the population. An estimator is a random variable, because its value depends on which particular sample is obtained, which is random. A canonical example of an estimator is the sample mean, which is an estimator of the population mean....

14. Estimator
    In statistics, an `estimator` is a rule for calculating an estimate of a given quantity based on observed data: thus the rule and its result (the estimate) are distinguished. This article discusses estimators that are point estimators; that is, they yield single-valued results, although this include...
