literanger - Random Forests for Multiple Imputation Based on 'ranger'
An updated implementation of R package 'ranger' by Wright
et al, (2017) <doi:10.18637/jss.v077.i01> for training and
predicting from random forests, particularly suited to
high-dimensional data, and for embedding in 'Multiple
Imputation by Chained Equations' (MICE) by van Buuren (2007)
<doi:10.1177/0962280206074463>. Ensembles of classification and
regression trees are currently supported. Sparse data of class
'dgCMatrix' (R package 'Matrix') can be directly analyzed.
Conventional bagged predictions are available alongside an
efficient prediction for MICE via the algorithm proposed by
Doove et al (2014) <doi:10.1016/j.csda.2013.10.025>. Survival
and probability forests are not supported in the update, nor is
data of class 'gwaa.data' (R package 'GenABEL'); use the
original 'ranger' package for these analyses.
