What accuracy statistics really measure
TL;DR: In this paper, it is shown that the mean magnitude relative error (MMRE) and the number of predictions within 25% of the actual, pred(25) are measures of the spread and the kurtosis of the variable z, where z =estimate/actual.

What accuracy statistics really measure
TL;DR: It is demonstrated that MMRE and pred(25) are, respectively, measures of the spread and the kurtosis of the variable z, where z=estimate/actual.
Journal ArticleDOI
Factors that affect software systems development project outcomes: A survey of research
TL;DR: A survey of the research literature that has addressed this topic in the period 1996-2006, with a particular focus on empirical analyses is provided in this article, where a new classification framework that represents an abstracted and synthesized view of the types of factors that have been asserted as influencing project outcomes is presented.
Journal ArticleDOI
A comparison of techniques for developing predictive models of software metrics
TL;DR: The use of regression analysis to derive predictive equations for software metrics has recently been complemented by increasing numbers of studies using non-traditional methods, such as neural networks, fuzzy logic models, case-based reasoning systems, and regression trees.
