The misuse of the NASA metrics data program data sets for automated software defect prediction
Gray, D.; Bowes, David; Davey, N.; Sun, Yi; Christianson, B. (Institution of Engineering and Technology (IET), 2011)Background: The NASA Metrics Data Program data sets have been heavily used in software defect prediction experiments. Aim: To demonstrate and explain why these data sets require significant pre-processing in order to be ... -
Pepsinogen types in worm-free sheep and in sheep infected with Ostertagia circumcincta and Haemonchus contortus
Mostofa, M.; McKellar, Quintin; Eckersall, P. D.; Gray, D. (1990)Pepsinogen isolated from the plasma of Dorset wethers with abomasal burdens of Ostertagia circumcincta was found to have the same proportions of three zymogen subtypes as that isolated from the plasma of Merino wethers ... -
A Systematic Literature Review on Fault Prediction Performance in Software Engineering
Hall, Tracy; Beecham, Sarah; Bowes, David; Gray, D.; Counsell, S. (2012)Background: The accurate prediction of where faults are likely to occur in code can help direct test effort, reduce costs, and improve the quality of software. Objective: We investigate how the context of models, the ...
