Expectation, английский
- Математическое ожидание.
- Generally, the anticipation of something to occur at a certain time or place or in a certain way. in statistics, the probability of an event in a universe inferred from the relative frequency of observing that event in a sample.

Expectation theory, английский
Expectation, expected value, английский
The expected value of a random variable is the long-term limiting average of its values in independent repeated experiments. the expected value of the random variable x is denoted ex or e(x). for a discrete random variable (one that has a countable number of possible values) the expected value is the weighted average of its possible values, where the weight assigned to each possible value is the chance that the random variable takes that value. one can think of the expected value of a random variable as the point at which its probability histogram would balance, if it were cut out of a uniform material. taking the expected value is a linear operation: if x and y are two random variables, the expected value of their sum is the sum of their expected values (e(x+y) = e(x) + e(y)), and the expected value of a constant a times a random variable x is the constant times the expected value of x (e(a×x ) = a× e(x)).

Expectational inflation, английский

Expectations hypothesis theories, английский
Theories of the term structure of interest rates, which include the pure expectations theory; the liquidity theory of the term structure, and the preferred habitat theory. these theories hold that each forward rate equals the expected future interest rate for the relevant period. these three theories differ, however, on whether other factors also affect forward rates, and how.
Expectations theory of forward exchange rates, английский
A theory of foreign exchange rates that states that the expected future spot foreign exchange rate t periods from now equals the current t-period forward exchange rate.

Математическое ожидание, русский
- Математически рассчитанная величина среднего выигрыша или проигрыша, которых можно ожидать от данной ставки на длинной дистанции.
- , среднее значение, понятие теории вероятностей, важнейшая характеристика распределения значений случайной величины х. в простейшем случае, когда х может принимать лишь конечное число значений x1, x2, ..., xn с вероятностями p1, p2, ..., pn, математическим ожиданием величины х называется выражение: ех = x1p1 + x2p2 + ... + xnpn.
