Vincent average

From Wikipedia, the free encyclopedia

In applied statistics, Vincentization[1] was described by Ratcliff (1979),[2] and is named after biologist S. B. Vincent (1912),[3] who used something very similar to it for constructing learning curves at the beginning of the 1900s. It basically consists of averaging subjects' estimated or elicited quantile functions in order to define group quantiles from which can be constructed.

To cast it in its greatest generality, let represent arbitrary (empirical or theoretical) distribution functions and define their corresponding quantile functions by

The Vincent average of the 's is then computed as

where the non-negative numbers have a sum of .
