Software effort estimation in the early stages of the software life cycle is one of the most essential and daunting tasks for project managers. In this research, a new model based on non-linear regression analysis is proposed to predict software effort from use case diagrams. It is concluded that, where software size is classified from small to very large, one linear or non-linear equation for effort estimation cannot be applied. Our model with three different non-linear regression equations can incorporate the different ranges in software size.

使用非线性回归分析从用例图中估计软件工作量

在软件生命周期的早期阶段进行软件工作量估算是项目经理最重要和最艰巨的任务之一。在这项研究中，提出了一种基于非线性回归分析的新模型，以根据用例图预测软件工作量。得出的结论是，在软件规模从小到大分类的情况下，不能应用一个线性或非线性方程来估计工作量。我们具有三个不同非线性回归方程的模型可以包含软件大小的不同范围。
