A Treeboost Model For Software Effort Estimation Based On Use Case Points, Luiz Capretz, Ali Nassif
A Treeboost Model For Software Effort Estimation Based On Use Case Points, Luiz Capretz, Ali Nassif
Luiz Fernando Capretz
Software effort prediction is an important task in the software development life cycle. Many models including regression models, machine learning models, algorithmic models, expert judgment and estimation by analogy have been widely used to estimate software effort and cost. In this work, a Treeboost (Stochastic Gradient Boosting) model is put forward to predict software effort based on the Use Case Point method. The inputs of the model include software size in use case points, productivity and complexity. A multiple linear regression model was created and the Treeboost model was evaluated against the multiple linear regression model, as well as the …

Managing The Business Of Software Product Line: An Empirical Investigation Of Key Business Factors, Faheem Ahmed, Luiz Capretz
Luiz Fernando Capretz
Business has been highlighted as a one of the critical dimensions of software product line engineering. This paper’s main contribution is to increase the understanding of the influence of key business factors by showing empirically that they play an imperative role in managing a successful software product line. A quantitative survey of software organizations currently involved in the business of developing software product lines over a wide range of operations, including consumer electronics, telecommunications, avionics, and information technology, was designed to test the conceptual model and hypotheses of the study. This is the first study to demonstrate the relationships between …
