Multiple Imputation for Missing Data: Making the most of What you Know
通过模拟和案例分析，展示多重插补方法处理缺失数据，避免传统方法导致的统计推断偏差，适用于组织研究中的纵向流失或问卷未答问题。
Missing data are a common problem in organizational research. Missing data can occur due to attrition in a longitudinal study or nonresponse to questionnaire items in a laboratory or field setting. Improper treatments of missing data (e.g., listwise deletion, mean imputation) can lead to biased statistical inference using complete case analysis statistical techniques. This article presents a simulation and data analysis case study using a method for dealing with missing data, multiple imputation, that allows for valid statistical inference with complete case statistical analysis. Software for implementing multiple imputation under a multivariate normal model is freely and widely available (e.g., NORM, SAS, SOLAS). It should be routinely considered for imputing missing data. The authors illustrate the application of this technique using data from the HomeNet project.
