Model selection and model averaging on mortality of upper gastrointestinal bleed patients [PDF]

open access: yes, 2018
Model Selection (MS) is known to produce uncertainty into model-building process. Besides that, the process of MS is complex and time consuming. Therefore, Model Averaging (MA) had been proposed as an alternative to overcome the issues.
