Andres and Marzo's delta : ウィキペディア英語版 | Andres and Marzo's delta In statistics, Andrés and Marzo's Delta is a measure of an agreement between two observers used in classifying data. It was created by Andres & Marzo in 2004.〔Andrés, A Martín; Marzo, P. Femia (2004) "Delta: a new measure of agreement between two raters". ''British Journal of Mathematical and Statistical Psychology'', 57(1):1–19 〕 ==Rationale for use==
The most commonly used measure of agreement between observers is Cohen's kappa. The value of kappa is not always easy to interpret and it may perform poorly if the values are asymmetrically distributed. It also requires that the data be independent. The delta statistic may be of use when faced with the potential difficulties.
