Abstract

To define the reliability and usability of the linearity regression relationship between software size and effort, statistics analysis method was used to validate the regression result and seek for the reliability interval of coefficient b. The application method of the regression result was discussed under the situation that the regression result is usable. By analysis, it shows the result of the linearity regression relationship is ideal and has a high confidence level. The application of the linearity regression equation also proves that this regression relationship is effective and it could be applied in actual software projects. Therefore the equation could be used exactly during effort estimation of software projects.
