corrected quality ratio
The corrected quality ratio (Lindsey 1978) is a metric derived from the total citations and the total publications. It is calculated as:
$$CQ=\frac{C^P}{P}\sqrt{C^P \times P}$$which is the product of the mean number of citations per publication and the geometric mean of the numbers of citations and publications. It was designed to overcome problems with the mean citations per publication, particularly with respect to younger researchers.History
