Proportional reduction in loss

From Wikipedia, the free encyclopedia


Proportional reduction in loss (PRL) is a measure for data reliability (statistics) may be derived or evaluated. It was proposed by Bruce Cooil and Roland T. Rust in their 1994 paper. This measure is applicable when a researcher wants to assess the consensus between judges who are asked to code a number of items into mutually exclusive qualitative categories.
