“…Joshi (2017) notes that linear regression is not suitable for classification because it relies on linearly interconnected data, while decision tree is a compatible algorithm for classification. Most IPO performance research has been performed on linear regression models, but in this study we find previous research using the decision tree algorithm (Basti, Kuzey, & Delen, 2015;Chen, Chen, & Cheng, 2010;Chen & Cheng, 2012;Han, 2016;Quintana, Luque, Valls, & Isasi, 2012;Quintana, Sáez, & Isasi, 2017). We find that machine learning algorithms (the decision tree is known in this case as supervised learning) contain fewer error predictions than linear regression.…”
