缺失数据 Missing data(重定向自Missing value)
在统计调查的过程中,由于受访者对问题的遗漏、拒绝,或是调查员与调查问卷本身存在的一些疏忽,使得记录经常会出现 缺失数据 (Missing Data) 的问题。但是,几乎所有标准统计方法都假设每个个案具有可用于分析的所有变量信息,因此缺失数据就成为进行统计研究或问卷调查的工作人员所必须解决的一个问题。 Paul D. Allison在其2011年出版的Missing Data一书中,提到了许多解决缺失数据问题的方案,而它们各有利弊。

Missing data 缺失数据(重定向自Missing value)
In statistics, missing data, or missing values, occur when no data value is stored for the variable in an observation. Missing data are a common occurrence and can have a significant effect on the conclusions that can be drawn from the data. Missing data can occur because of nonresponse: no information is provided for several items or no information is provided for a whole unit. Some items are more sensitive for nonresponse than others, for example items about private subjects such as income. |
