This release contains one standard implementation of A12 effect size, for instance used in the following paper:
MINKU, L.; HOU, S.. "Clustering Dycom: An Online Cross-Company Software Effort Estimation Study", Proceedings of the 13th International Conference on Predictive Models and Data Analytics in Software Engineering (PROMISE), November 2017.
It also contains two temporal versions of A12, where A12 is computed multiple times across time. The window-based version (a12temporal2.m) was used in the following paper:
MINKU, L.L.; YAO, X. . "Which Models of the Past Are Relevant to the Present? A software effort estimation approach to exploiting useful past models", Automated Software Engineering Journal, v. 24, n. 7, p. 499-542, September 2017, doi: 10.1007/s10515-016-0209-7.
