Lesson 2 provides the overview of organizations for production, dissemination and coordination of official statistics. 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 … See more 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 … See more 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 outcomes, such as in the flip of a coin. With the theory of infinite series, this can be … See more The expectation of a random variable plays an important role in a variety of contexts.

WebDec 20, 2024 · The "e" is a symbol for base-10 scientific notation. The "e" stands for × 10 e x p o n e n t. So -1.861246e-04 means − 1.861246 × 10 − 4. In fixed-point notation that would be -0.0001861246. This notation is pretty standard. Even Microsoft Excel understands it, not just R. Share.

WebStatistics Expectation and Variance The expected value (or mean) of X, where X is a discrete random variable, is a weighted average of the possible values that X can take, each value being weighted according to the probability of that event occurring. The expected value of X is usually written as E (X) or m. E (X) = S x P (X = x) WebSep 22, 2024 · The mathematical constant e was coined by the 18th-century Swiss mathematician, Leonhard Euler.
