網路上的精選摘要

In statistics, an empirical distribution function (commonly also called an empirical Cumulative Distribution Function, eCDF) is the distribution function associated with the empirical measure of a sample. This cumulative distribution function is a step function that jumps up by 1/n at each of the n data points.

經驗分布函數 (Empirical distribution function)

简介

經驗分布函數是統計學中一個與樣本經驗測度有關的分布函數。該累積分布函數是在所有n個數據點上都跳躍1/n的階躍函數。對被測變量的某個值而言,該值的分布函數值表示所有觀測樣本中小於或等於該值的樣本所占的比例。 經驗分布函數是對用於生成樣本的累積分布函數的估計。 维基百科
