Multiple imputation is a popular technique for analyzing incomplete data. Missing at random mechanism is often assumed when multiple imputation is performed, assuming that the response mechanism does not depend
The MNAR statement imputes missing values by using the pattern-mixture model approach, assuming the missing data are missing not at random (MNAR), which is described in the section Multiple Imputation with Pattern-Mixture Models. By comparing inferential results for these values to results for impu...
任意缺失数据(arbitrary data missing, generalized pattern of missing data),是指数据集中的缺失模式没有特定的结构或规律,是指数据集中的缺失模式没有特定的结构或规律,数据缺失可以在任何时间点、任何变量上发生。这种是最常见的也是处理最麻烦的。 单调缺失数据(monotonic missing data,monotone missing data pattern...

Multiple imputation inference involves three distinct phases: 1. The missing data are filled in m times to generate m complete data sets. 2. The m complete data sets are analyzed by using standard SAS procedures. 3. The results from the m complete data sets are combined for the inference...
When 40% of the data were missing completely at random, the Type I error rates for the new methods were inflated, but not for lower percents.doi:10.1080/00220973.2015.1011594FinchW. HolmesRoutledgeJournal of Experimental EducationFinch, W. (2016). Missing data and multiple imputation in the ...
The aim of the study is to compare the performance of the multivariate normal imputation and the fully conditional specification methods, using real data set with missing data partially completed 2 years later. Method: The data used came from an ongoing randomized controlled trial with 5-year ...
