A Study on the Improvement of Software Effort Estimation

Software effort estimation is an importance task in software project management. This task is challenging. Accuracy of estimation is also essential for successful completion of any software project. This paper present a approach, it is to estimate the parameters of the linear model is ordinary least squares regression which has been extensively applied to various datasets. The least squares estimation takes into account only the error arising from the dependent variable (effort), while the measurement of independent variable (size) is considered free of errors.
