Witryna11 maj 2024 · 3. If you could take the mode (you can't here), its called MAP (Maximum a Posteriori) estimate. It's a common point estimator (may not be the best sometimes). If you take the expected value/mean it's called conditional expectation given data, $\mathbb E [X \mathcal D]$ or the posterior mean, which is a commonly used point … WitrynaPoint estimator: any function W(X 1;:::;X n) of a data sample. The exercise of point estimation is to use particular functions of the data in order to estimate certain unknown population parameters. Examples: Assume that X 1;:::;X n are drawn i.i.d. from some distribution with unknown mean and unknown variance ˙2. Potential point estimators ...
