What do you mean by estimator? An "**estimator**" or " point estimate " is a statistic (that is, a function of the data) that is used to infer the value of an unknown parameter in a statistical model. The parameter being estimated is sometimes called the estimand.

The efficiency of an estimator is a measure of how 'tight' are it's estimates around the true population value of the parameter that it is estimating, as compared to a perfectly efficient estimator.
