Fisher information definition
WebDefinition. The Fisher information is the amount of information that an observable random variable X carries about an unobservable parameter θ upon which the likelihood function of X, L (θ) = f ( X ; θ), depends. The likelihood function is the joint probability of the data, the X s, conditional on the value of θ, as a function of θ. WebDec 18, 2024 · The definition of Fisher information matrix originated from classical statistics. For a probability distribution where is the conditional probability for the outcome result y , an entry of Fisher information matrix is defined as For discrete outcome results, it …
