R script for simulation study from the Entropy submission "Analyzing the Effect of Imputation on Classification Performance under MCAR and MAR Missing Mechanisms".
Datasets used in simulation study were obtained from the OpenML Project (https://www.openml.org/) and the UCI Machine Learning Repository (https://archive.ics.uci.edu/ml/index.php).
The R code is designed for use with a SLURM cluster. For licensing reasons, the original datasets were not included in this repository. For our simulation, they were embedded within a mlr task (see: https://cran.r-project.org/web/packages/mlr/index.html). For successfully running the code, these individual classification tasks need to be created first using the makeClassifTask() function from mlr.
