Skew-Normal Distribution In its simplest reading, the term "skew-normal" refers to a family of continuous probability distributions on the real line having density function of form $$\\phi (z;\\alpha ) = 2\\:\\phi (z)\\;\\Phi... A Azzalini - Springer Berlin Heidelberg 被引量: 11...
In this example, we depict the standard normal distribution, with μ = 0 and σ = 1. 在这个示例中,我们展示的是 标准正态分布 (standard normal distribution),其中μ=0,σ=1 正态分布由两个参数控制, 。 Literature The PHI() function returns value of the distribution function for a standar...

form 1$$\phi (z;\alpha ) = 2\:\phi (z)\;\Phi (\alpha z),\qquad (-\infty <\infty ),$$ where ϕ (⋅) and Φ( ⋅) denote the { N}(0, 1) density and cumulative distribution function, respectively, and α is a real parameter which regulates the shape of the density....
Cumulative Distribution Function FormulaIn every probability distribution, including normal distributions, the area under the curve is defined by a cumulative distribution function, or CDF. For a standard normal distribution, the CDF formula[4] denoted by the Greek letter phi (Φ) is: ...
