To calculate the recall for a given class, we divide the number of true positives by the prevalence of this class (number of times that the class occurs in the data sample). The class-wise precision and recall values can then be combined into an overall multi-class evaluation score, e.g., using the macro F1 metric. [21]
Precision and recall. In statistical analysis of binary classification and information retrieval systems, the F-score or F-measure is a measure of predictive performance. It is calculated from the precision and recall of the test, where the precision is the number of true positive results divided by the number of all samples predicted to be positive, including those not identified correctly ...
An example of a Levey–Jennings chart with upper and lower limits of one and two times the standard deviation. A Levey–Jennings chart is a graph that quality control data is plotted on to give a visual indication whether a laboratory test is working well. The distance from the mean is measured in standard deviations.
Positive recall is a term used in quality systems, most notably ISO9000.It is part of receiving inspection procedures. [1] It defines the concept that if a producer or manufacturer receives a product or process that requires inspection and it wishes to postpone the inspection process, it must have a system in place that will ensure that the postponed inspection process will take place at some ...

They are used for laboratory quality control, in "runs" consisting of measurements of multiple samples. They are a set of modified Western Electric rules , developed by James Westgard and provided in his books and seminars on quality control. [ 1 ]
