章节摘录

版权页：插图：Missing data are termed missing at random （MAR） if the missing values of Y depend on X,  but not on Y In other words, the observed Y values represent a random sample of the actual Y  values for each value of X, but the observed data for Ydo not necessarily represent a truly ran-  dom sample of all Y values. Even though the missing data process is random in the sample, its  values are not generalizable to the population. Most often, the data are missing randomly  within subgroups, but differ in levels between subgroups. The researcher must determine the  factors determining the subgroups and the varying levels between groups.For example, assume that we know the gender of respondents （the X variable） and are  asking about household income （the Y variable）. We find that the missing data are random for  both males and females but occur at a much higher frequency for males than females. Even  though the missing data process is operating in a random manner within the gender variable,  any remedy applied to the missing data will still reflect the missing data process because gen-  der affects the ultimate distribution of the household income values.A higher level of randomness is termed missing completely at random （MCAR）. In these  instances the observed values of Y are truly a random sample of all Y values, with no underly-  ing process that lends bias to the observed data. In simple terms, the cases with missing data  are indistinguishable from cases with complete data.From our earlier example, this situation would be shown by the fact that the missing  data for household income were randomly missing in equal proportions for both males and  females. In this missing data process, any of the remedies can be applied without making  allowances for the impact of any other variable or missing data process.Diagnostic Tests for Levels of Randomness. As previously noted, the researcher must ascer-tain whether the missing data process occurs in a completely random manner. When the data set issmall, the researcher may be able to visually see such patterns or perform a set of simple calculations（such as in our simple example at the beginning of the chapter）. However, as sample size and the num-ber of variables increases, so does the need for empirical diagnostic tests. Some statistical programsadd techniques specifically designed for missing data analysis （e.g., Missing Value Analysis in SPSS）,which generally include one or both diagnostic tests.The first diagnostic assesses the missing data process of a single variable Y by forming twogroups: observations with missing data for Y and those with valid values of Y. Statistical testsare then performed to determine whether significant differences exist between the two groupson other variables of interest. Significant differences indicate the possibility of a nonrandommissing data process.Let us use our earlier example of household income and gender. We would first form twogroups of respondents, those with missing data on the household income question and thosewho answered the question. We would then compare the percentages of gender for each group.If one gender （e.g., males） was found in greater proportion in the missing data group, we wouldsuspect a nonrandom missing data process. If the variable being compared is metric （e.g., anattitude or perception） instead of categorical （gender）, then t-tests are performed to determinethe statistical significance of the difference in the variable's mean between the two groups. Theresearcher should examine a number of variables to see whether any consistent patternemerges. Remember that some differences will occur by chance, but either a large number or asystematic pattern of differences may indicate an underlying nonrandom pattern.A second approach is an overall test of randomness that determines whether the missing datacan be classified as MCAR.

•   这本是应用类多元里一本写得比较好的，很细致，结构我比较喜欢，但是做教材不行，毕竟是英文版。我觉得适合研究生和专业人士看，本科英语好的也可尝试。
•   书本身质量很好，摸起来也很舒服。
•   书很好，内容也给力！
•   蛮好的书哦 原版的原汁原味些 希望能读懂啊
•   作为一名市场营销的研究生，能够灵活地分析数据，得出决策判断的依据，很有必要学习一下！
•   适合初学者自学，前提是英语基础不错，或愿意尝试
•   这本书是国际版，章节安排上与美国本土版本有所不同，但内容基本一致。封面用的是本土版的封面，还是显得出版社不太诚实。这本书基本没有公式，实际上是想用文字语言把多元统计的原理说清楚。网上有配套材料，包括SPSS格式的数据和各章的SPSS SYNTAX文件。如果你的英语理解能力足够好，并且有SPSS和基础统计学的基础，这本书能用作自学，像有些网友称之为多元数据分析的“圣经”也不过分。但是，如果你缺乏这些基础，自学就比较难了。其实这样的书真适合有国外教育背景的统计学家或社会科学家来翻译。希望出版社能在这方面做些努力。
•   挺好的一本书，就是全英文，理解有点难度，头脑一热买的
•   多元数据分析工人的bible
•   Nice book and very useful.
