One of the greatest challenges for software developers is forecasting the development effort for a software system for the last decades. The capability to provide a good estimation on software development efforts is necessitated by the project managers. Software effort estimation model divided into two main categories: algorithmic and nonalgorithmic. These models too have difficulty in modeling...

Software undergoes changes at all stages of the software development process. Accepting too many changes will cause expense and delay and rejecting the changes may cause customer dissatisfaction. One of the inputs that help the software project management to decide whether to accept or reject the changes is by having a reliable estimation of the change effort. From a software development perspe...

Software engineering is the discipline which paves the road map for the development of software within the given schedule and effort with the desired quality. The process begins with estimating the size, effort and time required for the development of the software and ends with the product. In most existing research on the effort estimation, the Function Point Analysis (FPA) method is used to e...

When applying estimation methods, the issue of outliers is inevitable. The extent their influence has not been clarified, though several studies have evaluated outlier elimination methods. It unclear whether we should always be sensitive to outliers, removed before estimation, and what amount precaution required for collecting project data. Therefore, goal this study illustrate a guideline that...
