To estimate software effort according to software size, statistical analysis was held using the historical project data. The tool statistics method and the programming statistics method were adopted independently for linearity regression analysis. After the regression analysis, the linearity regression equation was obtained. The final studies showed that the outcomes obtained by these two methods...
To ensure the estimation accuracy of software project schedule and improve the timely completion of the projects, a quantitative estimation guide of software project was studied combined with some actual project cases. A non-linear regression curve was obtained by the use of statistical analysis methods, on base of this a schedule estimation guide model was built and the use of the model was studied...
