Statistical ratios | Regression diagnostics

Pseudo-R-squared

Pseudo-R-squared values are used when the outcome variable is nominal or ordinal such that the coefficient of determination R2 cannot be applied as a measure for goodness of fit. In linear regression, the squared multiple correlation, R2 is used to assess goodness of fit as it represents the proportion of variance in the criterion that is explained by the predictors. In logistic regression analysis, there is no agreed upon analogous measure, but there are several competing measures each with limitations. Four of the most commonly used indices and one less commonly used one are examined in this article: * Likelihood ratio R2L * Cox and Snell R2CS * Nagelkerke R2N * McFadden R2McF * Tjur R2T (Wikipedia).
