(ii) “Branch Scatter has a negative impact on software quality.”
(iii) “Branch Scatter Entropy has a slight positive impact on software quality in Windows Vista and negative impact on software quality in Windows 7.”
(iv) “Branch Depth and Branch Depth Entropy have very little or no impact on software quality.”
