A Trend Prediction of Code Churn in Open Source Development -- An Application of Growth Curve Model --
Hirohisa Aman (Ehime Univ.) SS2009-47
Abstract (in Japanese) (See Japanese page) 
(in English) Source code is a basic product reflecting a status of an open source development.
A quantitative understanding of source code churn trends will be important to make an assessment and/or a prediction about the software quality and the development project.
Toward the achievement of the quantitative understanding, this paper studies some mathematical models in which a code change is considered to be a probability event --- the mathematical models are the exponential growth model, the delayed S-shaped growth model and the inflection S-shaped growth model, that are based on the non-homogeneous Poisson process.
The empirical study using Eclipse source code shows that the inflection S-shaped growth model has been well fitted to actual code churn trends, but some important future work have been found out as well.
