A geometric series is sometimes called ageometric sequenceor ageometric progression. They all mean the same thing: a listing of numbers that follow a specific pattern. The pattern is regulated by the common ratio, which is the number that is the ratio between consecutive numbers in the series....
The following Excel 2007 worksheet formula is equivalent to =NEGBINOM.DIST(5,1,.2,TRUE) =SUMPRODUCT(NEGBINOMDIST(ROW(INDIRECT(“1:6”))-1,1,0.2)) and so has the value 0.737856. This formula works since the INDIRECT array function takes a string with a cell o...
3) geometric iterative mean 几何迭代平均值 1. This paper generalized a class of arithmetic iterative mean, geometric iterative mean in the generalized weighted of and harmonic iterative mean, and then gave the definition,the calculation formula, the equality relations, inequality relations of them, ...
where dx denotes the last change, α is the speed of mean reversion, x- is the expected return and σ is the dispersion (variance) parameter. dz is a Weiner process with mean 0 and standard deviation t. We may reformulate Equation 7.2.1 in terms of the change in price from period to...
This table contains the mean return (μ) and standard deviation (σ) of the daily returns estimated using Equation (3) at both the daily and weekly frequency. The formulae used for them are shown in Equations (4) and (5), respectively. These are standard formulae that are normally used...
