Abstract—In an interesting paper, Laranjeira [3] describes a first attempt to understand cost estimation within an object-oriented environment. While the presented approach presents many interesting and useful ideas, it is, unfortunately, marred by several mathematical errors pertaining to statistics, exponential functions, and the nature of discrete vs. continuous data. These are discussed here and more appropriate-correct procedures outlined.
