Estimator
In statistics, an estimator is a function of the observable sample data that is used to estimate an unknown population parameter; an estimate is the result from the actual application of the function to a particular set of data. Many different estimators are possible for any given parameter. Some criterion is used to choose between the estimators, although it is often the case that a criterion cannot be used to clearly pick one estimator over another. To estimate a parameter of interest (e.g., a population mean, a binomial proportion, a difference between two population means, or a ratio of two population standard deviation), the usual procedure is as follows:Select a random sample from the population of interest.Calculate the point estimate of the parameter.Calculate a measure of its variability, often a confidence interval.Associate with this estimate a measure of variability.

Estimateur (statistique)
En statistique inférentielle, un estimateur est une valeur calculée sur un échantillon et que l'on espère être une bonne évaluation de la valeur que l'on aurait calculée sur la population totale. On cherche à ce qu'un estimateur soit sans biais, convergent, efficace et robuste.
