Density Function The Generalized Gaussian density has the following form: where  (rho) is the "shape parameter". The density is plotted in the following figure: Matlab code used to generate this figure is available here: ggplot.m. Adding an arbi…

The Basics of Probability Probability measures the amount of uncertainty of an event: a fact whose occurence is uncertain. Sample space refers to the set of all possible events, denoted as . Some properties: Sum rule: Union bound: Conditional probabi…

一起啃PRML - 1.2.4 The Gaussian distribution 高斯分布 正态分布 @copyright 转载请注明出处 http://www.cnblogs.com/chxer/ 我们将用整个第二章来研究各种各样的概率分布以及它们的性质.然而,在这里介绍连续变量一种最重要的概率分布是很方便的.这种分布就是正态分布(normal distribution)或者高斯分布(Gaussian distribution).在其余章节中(事实上在整本书中),我们将会经常用到这种分布.…

. 1.What is a Chi Square Test? 卡方检验有两种类型.两者使用卡方统计量和分布的目的不同. 第一种:卡方拟合优度检验确定样本数据是否与总体匹配.(这里不介绍) 第二种:独立性的卡方检验比较列联表中的两个变量,看看它们是否相关.在更一般的意义上,它测试分类变量的分布是否不同. 一个非常小的x平方分布测试统计量意味着您观察到的数据非常适合您的预期数据.换句话说,之间有关系. 非常大的x平方分布测试统计量意味着数据不太适合.换句话说,之间没有关系. There are tw…

UNDERSTANDING THE GAUSSIAN DISTRIBUTION Randomness is so present in our reality that we are used to take it for granted. Most of the phenomena which surround us have been generated by random processes. Hence, our brain is very good at recognise these…
