Webb9 juni 2024 · If you have a formula describing the distribution, such as a probability density function, the expected value is usually given by the µ parameter. If there’s no µ … In probability theory, the expected value (also called expectation, expectancy, mathematical expectation, mean, average, or first moment) is a generalization of the weighted average. Informally, the expected value is the arithmetic mean of a large number of independently selected outcomes of a random variable. The … Visa mer The idea of the expected value originated in the middle of the 17th century from the study of the so-called problem of points, which seeks to divide the stakes in a fair way between two players, who have to end their game before it … Visa mer As discussed above, there are several context-dependent ways of defining the expected value. The simplest and original definition deals with the case of finitely many possible … Visa mer The expectation of a random variable plays an important role in a variety of contexts. For example, in decision theory, an agent making an optimal choice in the context of incomplete information is often assumed to maximize the expected value of their Visa mer • Edwards, A.W.F (2002).
