In these types of regression methodology, variable selection is one of the most important issues to construct a robust and predictive quantitative structure activity relationship (QSAR) model.
Additionally, the studies reviewed were variable in methodology, with variable thresholds for surgeon volume categorization.
In the proposed methodology, the variables defining the quality of construction, workmanship and exposure conditions are treated as fuzzy variables.
