Some Additional Multiple Imputation Functions, Especially for 'mice'


Contains functions for multiple imputation which complements existing functionality in R. In particular, several imputation methods for the mice package (van Buuren & Groothuis-Oudshoorn, 2011, <doi:10.18637/jss.v045.i03>) are implemented. Main features of the miceadds package include plausible value imputation (Mislevy, 1991, <doi:10.1007/BF02294457>), multilevel imputation for variables at any level or with any number of hierarchical and non-hierarchical levels (Grund, Luedtke & Robitzsch, 2018, <doi:10.1177/1094428117703686>; van Buuren, 2018, Ch.7, <doi:10.1201/9780429492259>), imputation using partial least squares (PLS) for high dimensional predictors (Robitzsch, Pham & Yanagida, 2016), nested multiple imputation (Rubin, 2003, <doi:10.1111/1467-9574.00217>), substantive model compatible imputation (Bartlett et al., 2015, <doi:10.1177/0962280214521348>), and features for the generation of synthetic datasets (Reiter, 2005, <doi:10.1111/j.1467-985X.2004.00343.x>; Nowok, Raab, & Dibben, 2016, <doi:10.18637/jss.v074.i11>).


  • The miceadds package contains some functionality for imputation of multilevel data. The function mice.impute.ml.lmer is a general function for imputing multilevel data with hierarchical or cross-classified structures for variables at an arbitrary level. This imputation method uses the lme4::lmer function in the lme4 package. The imputation method mice.impute.2lonly.function conducts an imputation for a variable at a higher level for already defined imputation methods in the mice package. Two-level imputation is available in several functions in the mice package (mice::mice.impute.2l.pan, mice::mice.impute.2l.norm) as well in micemd and hmi packages. The miceadds package contains additional imputation methods for two-level datasets: mice.impute.2l.continuous for normally distributed data, mice.impute.2l.pmm for predictive mean matching in multilevel models and mice.impute.2l.binary for binary data.

  • In addition to the usual mice imputation function which employs parallel chains, the function mice.1chain does multiple imputation from a single chain.

  • Nested multiple imputation can be conducted with mice.nmi. The function NMIcombine conducts statistical inference for nested multiply imputed datasets.

  • Imputation based on partial least squares regression is implemented in mice.impute.pls.

  • Unidimensional plausible value imputation for latent variables (or variables with measurement error) in the mice sequential imputation framework can be applied by using the method mice.impute.plausible.values.

  • Substantive model compatible multiple imputation using fully conditional specification can be conducted with mice.impute.smcfcs.

  • The function syn_mice allows the generation of synthetic datasets with imputation methods for mice. It has similar functionality as the synthpop package (Nowok, Raab, & Dibben, 2016). The function mice.impute.synthpop allows the usage of synthpop synthesization methods in mice, while syn.mice allows the usage of mice imputation methods in synthpop.

  • The method mice.impute.simputation is a wrapper function to imputation methods in the simputation package. The methods mice.impute.imputeR.lmFun and mice.impute.imputeR.cFun are wrapper functions to imputation methods in the imputeR package.

  • The miceadds package also includes some functions R utility functions (e.g. write.pspp, ma.scale2).

  • Imputations for questionnaire items can be accomplished by two-way imputation (tw.imputation).
