Statistical hypothesis testing is a key technique of both frequentist inference and Bayesian inference, although the two types of inference have notable differences. Statistical hypothesis tests define a procedure that controls (fixes) the probability of incorrectly deciding that a default position (null hypothesis) is incorrect. The procedure is based on how likely it would be for a set of observations to occur if the null hypothesis were true. This probability of making an incorrect …

Webbis defined as the expected value of the squared errors. It is used to indicate how far, on average, the collection of estimates are from the single parameter being estimated . Suppose the parameter is the bull’s-eye of a target, the estimator is the process of shooting arrows at the target, and the individual arrows are estimates (samples).
