%description
A framework that boosts the imputation of 'missForest' by Stekhoven, D.J.
and Bühlmann, P. (2012) <doi:10.1093/bioinformatics/btr597> by harnessing
parallel processing and through the fast Gradient Boosted Decision Trees
(GBDT) implementation 'LightGBM' by Ke, Guolin et al.(2017)
<https://papers.nips.cc/paper/6907-lightgbm-a-highly-efficient-gradient-boosting-decision>.
'misspi' has the following main advantages: 1. Allows embrassingly
parallel imputation on large scale data. 2. Accepts a variety of machine
learning models as methods with friendly user portal. 3. Supports multiple
initializations methods. 4. Supports early stopping that prohibits
unnecessary iterations.
