5. 假设检验 久经考场的你肯定对于很多概念类题目里问到的“区别和联系”不陌生,与之类似,在统计领域要研究的是数据之间的区别和联系,也就是差异性分析和相关性分析。本节我们重点关注数据的差异性分析。 我们知道,比较两个数之间的大小,要么前后两者求差,要么求比。差值大于零说明前者大于后者。比值大于1说明分子...

In addition to the number ofttest options,ttests are often confused with completely different techniques as well. Here's how to keep them all straight. Correlation and regressionare used to measure how much two factors move together. Whilettests are part of regression analysis, they are focused...
