The meaning of F DISTRIBUTION is a probability density function that is used especially in analysis of variance and is a function of the ratio of two independent random variables each of which has a chi-square distribution and is divided by its number of
The probability density function must therefore be rectangular, as shown in Fig. 10.4(b). Since the probability of the waveform having an amplitude in the range ±X is 1, that is, ∫-XXp(x)dx = 1the area of the rectangle in Fig. 10.4(b) is 1, and since its width is 2X, ...

高斯分布(Gaussian Distribution)的概率密度函数(probability density function) 对应于numpy中: 参数的意义为: 我们更经常会用到的np.random.randn(size)所谓标准正态分布(μ=0,σ=1μ=0,σ=1),对应于np.rando
Combining what wikipedia and my own interpretation, probability distribution function can mean probability density function (in the context of continuous random variables) or probability mass function (in the context of discrete random variables). Therefore, it is recommended not to use probability distri...

在这种场合,由每个随机变量的(边际)分布函数可以唯一地确定联合分布函数(Joint Distribution Function)。 对于离散型随机变量,(1)等价于任何一组可能取的值(x1,…,xn)成立 对于连续型随机变量,条件(1)的等价形式是对一切x1,…,xn成立 这里f(x1,…,xn)是联合分布密度函数(Joint density function),而fi(xi)是各...
