estimator
An estimator is a crucial component in the field of data science and machine learning. It is a function that estimates the value of an unknown parameter based on a given set of data. Estimators are used to make predictions, perform analysis, and make decisions based on data.
There are two main types of estimators: point estimators and interval estimators. A point estimator provides a single value as an estimate of the parameter. For example, the sample mean is a point estimator for the population mean. An interval estimator, on the other hand, provides a range of values within which the parameter is likely to lie. For example, a 95% confidence interval provides a range of values within which the population mean is likely to lie with 95% confidence.
Estimators can be classified into two categories based on their nature: parametric estimators and non
