https://www.pianshen.com/article/95711145637/ 一、累积分布函数(Cumulative Distribution Function) 累积分布函数(Cumulative Distribution Function),又叫分布函数,是概率密度函数的积分,能完整描述一个实随机变量X的概率分布。 一般以大写CDF标记,与概率密度函数probability density function(小写pdf)相对。 累计分布函数...
Standard Deviation: Distribution’s standard deviation. Cumulative: The logical value that specifies the distribution type to be used. If the cumulative value is "true," the cumulative normal distribution function (CDF) is returned. If the cumulative value is "false," the probability density functio...
Also, the search must be sufficiently refined that it "homes in" on an appropriate answer. To use the textbook Normal probability distribution table as an analogy, entries in the table must be accurate. Also, the table must contain so many entries that you can find the appropriate row of ...

Normal Probability Plot:正态概率散点图; Norm-score:正态值;z-score:z-值; 【参照书中第60页的图】 图 对数收益数据的正态分布散点图 假设观测值放在Data表的名为dvec的区域中。在VBA代码中,数组变量dvec用于存储单元格区域dvec中的数据。由于我们需要对数组元素dvec(i)进行处理,因此需将dvec声明为...
Excel中有一个内置函数叫做“高斯函数”(Gauss函数),它是基于高斯分布(Gaussian distribution)的概率密度函数(probability density function)所得到的。 这个函数的语法为GAUSS(x),其中x代表要计算高斯函数的值。高斯函数的返回值为0.5 * (1 + ERF(x / sqrt(2))),其中ERF(x)代表误差函数(error function),sqrt...
Use the probability calculator to compute for a given distribution function, the density function, the cumulative distribution function, or the inverse cumulative distribution function. Available in Excel with the XLSTAT software.
BETADIST Returns the beta cumulative distribution function BETAINV Returns the inverse of the cumulative distribution function for a specified beta distribution BINOMDIST Returns the individual term binomial distribution probability CHIDIST Returns the one-tailed probability of the chi-squared distribution ...
If cumulative is true, LogNorm_Dist returns the cumulative distribution function; if false, it returns the probability density function. Returns Double Remarks If any argument is nonnumeric, LogNorm_Dist returns the #VALUE! error value. If x ≤ 0 or if standard_dev ≤ 0, LogNorm_D...
The NORM.S.DIST Function is categorized under Excel Statistical functions. It will calculate the Excel Standard Normal Distribution function for a given value. The NORM.S.DIST function can be used to determine the probability that a random variable that
