Software development effort estimation is essential for software project planning and management. In this study, we present a spectral clustering algorithm based on symmetric matrixes as an option data processing. It expected that constructing model more similar can increase the accuracy. The research methods employ symmetrical processing experimentation. Four experimental models function point...

Replication studies increase our confidence in previous results when the findings are similar each time, and help mature knowledge by addressing both internal external validity aspects. However, these still rare certain software engineering fields. In this paper, we replicate extend a study, which denotes current state-of-the-art for multi-objective effort estimation, namely CoGEE. We investiga...
