Cohen

WebCohen's kappa statistic is an estimate of the population coefficient: κ = P r [ X = Y] − P r [ X = Y X and Y independent] 1 − P r [ X = Y X and Y independent] Generally, 0 ≤ κ ≤ 1, although negative values do occur on occasion. Cohen's kappa is ideally suited for nominal (non-ordinal) categories. WebApr 22, 2024 · The coefficient of determination is a number between 0 and 1 that measures how well a statistical model predicts an outcome. The coefficient of determination is often written as R2, which is pronounced as “r squared.” For simple linear regressions, a lowercase r is usually used instead ( r2 ).
