I n this d a y of “faster, cheaper, better” release cycles, software developers must focus enhancement efforts on those modules that need improvement the most. Predict ions of which modules are likely t o have faults during operations is an important tool t o guide such improvem ent efforts during maint en ance. Tree-based models are attractive because they readily model nonmonotonic relationships between a response variable and predictors. However, tree-based models are vulnerable t o… CONTINUE READING
