2.3 Generating Missing Values
We constructed synthetic datasets with up to 30% missing values by applying the following three missingness mechanisms on complete datasets: MCAR, MAR and MNAR. The implementations of these mechanisms are modified from [20].
MCAR. It was introduced by randomly removing 30% of the observations from each feature.
MAR. First, we select all observations within the 30-th percentile range of an independent feature (usually the first column in the dataset). Then, we randomly remove 60% observations from each corresponding (dependent) feature.
MNAR. We remove the observations of a feature if the observations fall within the 30-th percentile range of the feature value.
