This study used Weka (Waikato Environment for Knowledge
Analysis) for data mining task. Weka is a collection of machine
learning algorithm for pre-processing, classification,
regression, clustering, association rules, and visualization. Because Weka
belongs to open source software and several studies
have applied to analyze, we used the classification (logistic
regression, decision tree and artificial neural network) and
clustering (K-means) methods in Weka to analyze our dataset
[16–18].
