WebCox-Snell’s R squared uses the likelihood (as opposed to the log-likelihood), so some additional mathematical manipulation would be required to calculate this value. Unlike other pseudo R squared values here, the maximum of Cox-Snell’s R squared is less than 1. However, this value is commonly reported by other software, and so is an option ...

"WebMany pseudo R-squared models have been developed for such purposes (e.g., McFadden's Rho, Cox & Snell). These are designed to mimic R-Squared in that 0 means a bad model and 1 means a great model. However, they are fundamentally different from R-Squared in that they do not indicate the variance explained by a model. For example, if McFadden's ... " - Cox & snell r2

WebCox and Snell (1989, pp. 208–209) propose the following generalization of the coefficient of determination to a more general linear model: where is the likelihood of the intercept-only model, is the likelihood of the specified model, is the sample size, is the frequency of the th observation, and is the number of trials when events/trials ...
