Regression Models of Software Development Effort Estimation Accuracy and Bias

  title={Regression Models of Software Development Effort Estimation Accuracy and Bias},
  author={Magne J\orgensen},
  journal={Empirical Software Engineering},
This paper describes models whose purpose is to explain the accuracy and bias variation of an organization’s estimates of software development effort through regression analysis. We collected information about variables that we believed would affect the accuracy or bias of estimates of the performance of tasks completed by the organization. In total, information about 49 software development tasks was collected. We found that the following conditions led to inaccuracies in estimates: (1… CONTINUE READING
