Using SAS® for Multiple Imputation and Analysis of

The SAS multiple imputation procedures assume that the missing data are missing at random (MAR) that is the probability that an observation is missing may depend on Y obs but not on Y mis (Rubin 1976; 1987 p 53) For example consider a trivariate data set with variables Y 1 and Y 2 fully observed and a variable Y 3 that has missing values

What is using SAS for multiple imputation and analysis of data?

“Using SAS for Multiple Imputation and Analysis of Data” presents use of SAS to address missing data issues and analysis of longitudinal data. Appropriate multiple imputation and analytic methods are evaluated and demonstrated through an analysis application using longitudinal survey data with missing data issues.

What is multiple imputation of missing data?

Multiple Imputation of Missing Data Using SAS for an arbitrary missing data pattern can be employed. As with any imputation problem, the recommended imputation method depends on the pattern of missing data and the type of variables to be imputed. 1.3 Item Missing Data Mechanisms

Is there a macro for performing multilevel imputation?

Although multiple imputation does not suffer from this limitation, most software packages (including SAS®) include only single-level multiple imputation procedures. This paper aims to make the analysis of incomplete multilevel data easier by presenting a new SAS macro for performing multilevel imputation, MMI_IMPUTE.

What are the criticisms of the multiple imputation method?

The most valid criticisms of the multiple imputation method (Fay 1996; Kim et al. 2006) have zeroed in on the notion that the imputer's statistical model for the imputation might be very different from the data models of interest to the many data analysts who will subsequently use the multiply imputed data. For example, in y kmis, y kmis, 14
