Multiple Imputation for Missing Data: Making the Most of What You Know
通过模拟和案例分析，展示了多重插补方法在处理组织研究中常见缺失数据时的有效性，帮助研究者避免不当处理导致的统计推断偏差。
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.
