Therefore, it is a positive association. In Problem 2, the line is moving down. That is called a negative association. No association is like in Problem 3, when there isn't a clear line at all. I hope this helps!

WebWhat you have is therefore probably a true positive rate and a false negative rate. The distinction matters because it emphasizes that both numbers have a numerator and a denominator. Where things get a bit confusing is that you can find several definitions of “false positive rate” and “false negative rate”, with different denominators. http://compilers.cs.ucla.edu/papers/balancing-callgraphs.pdf

WebExercise 4. Employees of the company XYZ undergo regular drug tests. The test the company is using is known to have 1% false positive rate (i.e. the chance of marking a non-drug user as a drug user) and 5% false negative rate (i.e. the chance of marking a drug user as a non- drug user). Employee A tested positive and is now facing contract termination. WebWe achieve this goal by automatically producing a call-graph pruner through an automatic, ahead-of-time learning process. We added such a call-graph pruner to a software tool for null-pointer analysis and found that the false-positive rate decreased from 73% to 23%. This improvement makes the tool more useful to developers.
