The Project Management Institute, however, endorses the accepted convention that a negative variance is a bad thing, and a positive variance a good thing. A variance is the difference between the projected budget and the actual performance for a particular account. A negative variance means that the budgeted amount was greater than the actual amount spent. A positive variance means that the budgeted amount was less than the actual amount spent. Note there is some debate over whether a negative variance means an underrun or an overrun.
Likelihood ratios are proportions of probabilities. A likelihood ratio for a positive test result (LR+) is the ratio of the true positive rate (sensitivity) divided by the false-positive rate (1 - specificity). LR+ then can be thought of how much more likely the patient is to actually have the disease after a positive test result.
