Fit a distribution 分布
WebUse fit.st () to fit a Student t distribution to the data in djx and assign the results to tfit. Assign the par.ests component of the fitted model to tpars and the elements of tpars to nu, mu, and sigma, respectively. Fill in hist () to plot a histogram of djx. Fill in dt () to compute the fitted t density at the values djx and assign to yvals. WebSep 18, 2015 · 1.1 连续型随机变量的分布. 首先，我们来回顾一遍各类分布函数的表达式，及其关系。 先逐一介绍与标准正态分布相关的一些分布：正态分布，卡方分布， \(t-\) …

WebThe Anderson-Darling goodness-of-fit statistic (AD) is a measure of the deviations between the fitted line (based on the selected distribution) and the nonparametric step function … WebThe percent point function is the inverse of the cumulative distribution function and is. G(q) = F − 1(q) for discrete distributions, this must be modified for cases where there is no xk such that F(xk) = q. In these cases we choose G(q) to be the smallest value xk = G(q) for which F(xk) ≥ q . If q = 0 then we define G(0) = a − 1 .
