An Empirical Investigation of Relationship between Software Metrics

In this paper, we empirically explore the relationship between existing size and object oriented metrics with four quality measures i.e. abstractness, bug density, method to refactor and dead code over the different versions of an open source software JStock. In order to fulfil our goal, we performed an experiment on by calculating size and OO metrics for different versions of an open source software, analyze them and concluded the behavior over time. Next, we perform Pearson correlation analysis between the chosen metrics and four quality measures because exploring the strength of relationship between these metrics can suggest additional significant understandings than studying them in segregation.
