| From leankit, the simple model is if two people look at the same area of code and person a finds A bugs, person b finds B bugs and there are C bugs in common then using the Lincoln model an estimate for the total number of bugs in the code is (A * B) / C. The thinking here is that the more often you find common bugs the more likely it is that you have found all the bugs. | http://leankit.com/blog/2015/12/how-many-bugs-are-left-the-software-qa-puzzle/ | Intermediate |
