Supplemental Material for Pooling Methods for Likelihood Ratio Tests in Multiply Imputed Data Sets

A SAS Macro for Computing Pooled Likelihood Ratio Tests with Multiply Imputed Data

For multilevel analyses (e.g., linear mixed models), researchers are often interested in pooling, interpreting, and testing both fixed effects and random effects. PROC MIANALYZE has two shortcomings in this regard. First, it cannot easily pool variance estimates. Second, the significance tests of these estimates are Wald-type tests that are inappropriate for testing variance estimates. Likeliho...

Order selection tests with multiply imputed data

Nonparametric tests for the null hypothesis that a function has a prescribed form are developed and applied to data sets with missing observations. Omnibus nonparametric tests such as the order selection tests, do not need to specify a particular alternative parametric form, and have power against a large range of alternatives. More specifically, likelihood-based order selection tests are defin...

Analysis of Variance from Multiply Imputed Data Sets

The analysis of variance is a popular method used in many scientific applications. There are standard software for handling unbalanced data due to missing values in the outcome/dependent variable. The analysis becomes difficult when the missing values are in predictors. Multiple imputation is an increasingly popular method for handling such incomplete data. This approach involves replacing the ...
