Fig. 1.2 Instability in effort models: sorted β_i values from local calibration on 20*(66%) samples of NASA93 data. From [302]. Coefficients learned using Boehm's recommended methods [34]. A greedy backward selection removed attributes with no impact on estimates (so some attributes have less than 20 results). From [291]. 6

Fig. 1.3 Instability in defect models: studies reporting significant (“+”) or irrelevant (“−”) metrics verified by univariate prediction models. Blank entries indicate that the corresponding metric is not evaluated in that particular ...
