%description
We introduced a novel ensemble-based explainable machine learning model
using Model Confidence Set (MCS) and two stage Technique for Order of
Preference by Similarity to Ideal Solution (TOPSIS) algorithm. The model
combined the predictive capabilities of different machine-learning models
and integrates the interpretability of explainability methods. To develop
the proposed algorithm, a two-stage Technique for Order of Preference by
Similarity to Ideal Solution (TOPSIS) framework was employed. The package
has been developed using the algorithm of Paul et al. (2023)
<doi:10.1007/s40009-023-01218-x> and Yeasin and Paul (2024)
<doi:10.1007/s11227-023-05542-3>.
