The quality of the simulation of the motion and spread of a passive substance in a puff model depends on the ability to estimate the speed of the wind at the source height and standard deviation of concentration both in time and space. The wind profile is calculated using the standard Monin...
We obtain order estimates of deviations of Fourier sums, which are constructed depending on the behavior of functions that define the operator of generalized... D Zung - 《Ukrainian Mathematical Journal》 被引量: 10发表: 1992年 Moderate deviation principles for trajectories of sums of independent ...
aEquations (1) to (4) can be derived from the approaches and formulas for the recursive calculation of mean, variance, and standard deviation in References 5 to 7. 式(1)对(4)在参考5到7可以从方法和惯例获得为手段、变化和标准偏差的递归演算。[translate]...
aStatistical calculation function (max., min., mean value, standard deviation, upper limit value, lower limit value, passed number, range, NG number), Offset compensation 统计演算作用 (最大, min.,平均值,标准偏差,上限价值,低限价值,通过数字,范围, NG数字),垂距报偿 [translate] ...
The sum of squares measures the deviation of data points away from the mean value. A higher sum of squares indicates higher variability while a lower result indicates low variability from the mean. To calculate the sum of squares, subtract the mean from the data points, square the differences...

How to calculate standard deviation: Suppose that an investor has $600 to invest and is considering investing all of it in the shares of one firm, currently trading at $30. The investor assesses a 0.75 probability that the shares will increase in market value to $33 over the coming period...
Historical volatility (HV) is a statistical measure of thedispersionof returns for a given security ormarket indexover a given period of time. Generally, this measure is calculated by determining the average deviation from theaverage priceof a financial instrument in the given time period. Usingsta...
In addition to the forecast calculation, each example includes a simulated 2005 forecast for a three month holdout period (processing option 19 = '3') which is then used for percent of accuracy and mean absolute deviation calculations (actual sales compared to simulated forecast)....
