This paper demonstrates the existence of a bellwether effect in a number of software engineering domains such as: (1) defect prediction; (2) effort estimation; (3) code smell detection; and (4) issue lifetime estimation. This paper also shows that the bellwether effect can be leveraged to create a baseline transfer learner and that this baseline transfer learner can outperform several state of the art transfer learners.
