Do adaptation rules improve Web cost estimation?
http://www.ht03.org/papers/pdfs/29.pdf


From http://www.ht03.org/papers/
"Analogy-based estimation has, over the last 15 years, and particularly over
the last 7 years, emerged as a promising approach with comparable accuracy to,
or better than, algorithmic methods in some studies. In addition, it is
potentially easier to understand and apply; these two important factors can
contribute to the successful adoption of estimation methods within Web
development Companies We believe therefore, analogy-based estimation should be
examined further. This paper compares several methods of analogy-based effort
estimation. In particular, it investigates the use of adaptation rules as a
contributing factor to better estimation accuracy. Two datasets are used in the
analysis; results show that the best predictions are obtained for the dataset
that first, presents a continuous cost function, translated as a strong linear
relationship between size and effort, and second, is more unspoiled in terms of
outliers and collinearity. Only one of the two types of adaptation rules
employed generated good predictions."
