<p>CSV import</p> <p><b>New page</b></p><div>&#039;&#039;&#039;Estimator&#039;&#039;&#039; is a rule for calculating an estimate of a given quantity based on observed data: thus the rule (the estimator), the quantity of interest (the estimand) and its result (the estimate) are distinguished.<br /> <br /> There are point and interval estimators. The point estimators yield single-valued results, although this includes the possibility of single vector-valued results and results that can be expressed as a single function. This is in contrast to an interval estimator, where the result would be a range of plausible values (or vectors or functions).<br /> <br /> ==Types of Estimators==<br /> Estimators are applied in the fields of [[statistics]] and [[signal processing]]. There are several types of estimators, including:<br /> <br /> * [[Unbiased estimator|Unbiased Estimators]]<br /> * [[Minimum variance unbiased estimator|Minimum Variance Unbiased Estimators]]<br /> * [[Maximum likelihood estimator|Maximum Likelihood Estimators]]<br /> * [[Bayes estimator|Bayes Estimators]]<br /> * [[Method of moments (statistics)|Method of Moments Estimators]]<br /> <br /> ==Properties of Estimators==<br /> Estimators have certain properties that can be used to compare and evaluate them. These properties include:<br /> <br /> * [[Bias of an estimator|Bias]]<br /> * [[Variance]]<br /> * [[Efficiency (statistics)|Efficiency]]<br /> * [[Consistency (statistics)|Consistency]]<br /> <br /> ==Applications of Estimators==<br /> Estimators are used in various fields, including:<br /> <br /> * [[Econometrics]]<br /> * [[Machine learning]]<br /> * [[Signal processing]]<br /> * [[Data analysis]]<br /> <br /> ==See Also==<br /> * [[Estimation theory]]<br /> * [[Estimation of covariance matrices]]<br /> * [[Estimation of signal parameters]]<br /> * [[Estimation in statistics]]<br /> <br /> ==References==<br /> &lt;references /&gt;<br /> <br /> [[Category:Statistics]]<br /> [[Category:Signal processing]]<br /> [[Category:Machine learning]]<br /> [[Category:Econometrics]]<br /> {{stub}}<br /> {{dictionary-stub1}}</div>
