average, norm - a statistic describing the location of a distribution; "it set the norm for American homes" arithmetic mean, expected value, first moment, expectation - the sum of the values of a random variable divided by the number of values geometric mean - the mean of n numbers express...

As mentioned, Lindsay Lohan heads a great cast of young talent. This is my first encounter with this actress, and I'm fairly impressed by what she's done here. Although her performance isn't magnificent, teen starlets have come with an expectation of being rubbish recently, and Lindsay prov...
That is done by showing that the utility maximizing strategy of a CARA investor can be expressed in terms of expectation and the expected quadratic variation of the underlying price process. It coincides with the mean-variance optimal strategy if the underlying price process is a local martingale....
The arithmetic mean maintains its place in finance, as well. For example, mean earnings estimates typically are an arithmetic mean. Say you want to know the averageearningsexpectation of the 16analystscovering a particular stock. Simply add up all the estimates and divide by 16 to get the arit...
where the equation is supported by the law of iterated expectation. Hence, the distribution of Tξ(XX1,…,XXn) also converges to the distribution of W.Now, we will show that the drift terms Tn12(b) and Tn13(b) are negligible compared with Tn11(b). It is obvious that E(Tn12(b)...
arithmetic mean- the sum of the values of a random variable divided by the number of values expected value,first moment,expectation statistics- a branch of applied mathematics concerned with the collection and interpretation of quantitative data and the use of probability theory to estimate population...
In each term, Φ G G (i.e., the second set of Brownian W ( t ) ) is eliminated, hence this is a drastic simplification compared to the original 2 n dimensional joint expectation. A particular, fully solvable case is the FG model ( β i j = 0 , i , j = 1 , … , n )....
