Evaluating the effect of code duplications on software maintainability

Advances in Software Product Quality Measurement and its Applications in Software Evolution

“…Based on these requirements, we created a novel probabilistic approach that fullls all these requirements and thus improves the state-of-the-art methods. The theoretical background of the base model was elaborated by Bakota [10] with the author's participation primarily in the implementation and validation of the approach.…”

“…These models were able to estimate the maintainability of methods with a Pearson-correlation of 0.72 and a mean absolute error of 0.83 on a continuous [0,10] scale, where 0 means the absolutely unmaintainable and 10 means the perfectly maintainable source code. The focus of the improved case study was to nd out i) how eectively we could apply regression techniques to predict maintainability sub-characteristic on a continuous scale; and ii) how the prediction scores from regression models were aected by the underlying surveys (i.e.…”

“…The formalization of the proposed model is credited to Bakota [10]. As the author's main contribution is related to the empirical validation of the model, only a short summary of the formal approach is given in the thesis.…”

“…Then, in Section 3.2 a new probabilistic approach is presented that is able to handle the subjective interpretation of the term software quality and it translates it into a probabilistic distribution. The theoretical background of the base model was elaborated on by Bakota [10] with the author's participation primarily in the implementation and validation of the approach. After a short introduction to the mathematical formalism of the approach, in Section 3.4 we present the model created for measuring the quality of C# programs.…”

Maintainability of Source Code and its Connection to Version Control History Metrics

“…In his thesis Tibor Bakota [9] summarized the Columbus Quality Model itself, which is based on the Columbus Java analyzer tool. See Section 3.2.1 of this thesis for a summary.…”
