| Abstract(in English) | With the development of large and complex software, it may become difficult to proceed the project according to designed, due to its "quality", "cost", and "delivery". In software development, effort has been made to predict the schedule of administration. The prediction accuracy is improved by logarithmic transformation of variables, which is used to predict. However, it is not effective to transform all variables into logarithmic. It takes too much time and not realistic to check for each variable whether it should be transformed or not. It is efficient to select important variables which are expected to improve the prediction accuracy by transform into logarithmic compared to the case we transform for comparison. In the proposed method, we divided whole project into small sections, and determined the inclination in each divided segment, and decide whether the variable should be transform into logarithmic or not by the continuousness of increasing inclination. As a result, better prediction accuracy was obtained by our method, and the accuracy was higher compared to the case of techniques to compare. |
