一、大部分非参数方法是基于秩而不是原始数据。 二、参考: HollandWolfe和著

What is SPSS SPSS can take data from almost any type of file and use them to generate tabulated reports, charts, and plots of distributions and trends, descriptive statistics, and Introduction to SPSS complex statistical analysis SPSS makes statistical analysis convenient for the experienced user and approachable for the beginner

Simple Linear assumptions: Regression The relationship should be linear; and The level of data must be continuous Simple Linear Regression The regression equation (Bivariate Regression The purpose of simple linear regression is We already looked at measuring

Lecture 5 a distribution is a collection of scores order from lowest to highest value on the horizontal (X)axis, and in terms of T-Test frequency on the vertical (Y) axis. A ormal distribution sometimes referred to as a bell curve has a distribution that forms the shape of a bell. All you need to know to plot the normal distribution is the mean and standard deviation of the data This lecture covers

There are many contexts in which a variable is ordinal that have three or more Ordinal logistic Some typical examples are health status Regression ery good, good, So-So, bad, very bad) political ideology(very liberal, slightly iberal, moderate, slightly conservative very conservative), fertility intention(the

In many situations in demography and the ocial sciences however we have a dependent variable, Y, that is dichotomous Lecture 10 er or not a voman has had a second birth whether the econd birth is a male or a female baby Logistic Regression contraceptive method, whether or not a person has migrated in the last 5 years, whether

许多人简单地认为统计(Statistics)就是收集数字,其实这仅仅是统计学的原始意义。 现代统计学已远远超出了这个范围,发展成为广泛应用于社会科学、自然科学等领域的科学方法。它是研究客观事物数量特征和数量关系的方法论学科,能够告诉人们如何通过打开几扇窗口去探索一个未知的世界,教会人们怎样用一种新的方式来思考问题,是一门很实用的学科

第一章预备数学知识 第一节随机向量及其矩 第二节多元正态分布 第三节样本矩 第四节多元正态总体的均值与协差阵估计 第五节多元统计中常用的统计量及其分布

多元质量控制涉及到多元数据的整理和统计推断等复杂内 容。因此,掌握相应的多元统计概念和方法是讨论多元质量控制问 题的必要前提。 众所周知,一元统计质量控制是建立在一元正态分布基础上 的;因为在现实世界中产品和服务质量特性的统计量(随机变量) 大都服从或近似服从一元正态分布,或者它们的某种形式的极限 分布是…元正态分布同样,多元统计质量控制是以多元正态分布 理论为基础的;因为在现实世界中产品和服务的多重质量特性的 统计量(随机向量)都服从或近似服从多元正态分布,其某种形式 的极限分布也是多元正态分布因此,本章先用较大篇幅来讨论多 元正态变量的一些特征及多元正态样本函数的一些性质;
