WebIt’s worth noting that while Cox-Snell’s R squared takes a similar approach to McFadden’s R squared, the upper limit of Cox-Snell’s R squared isn’t 1; in fact, the upper limit in many cases can be much less than 1. That means that even if the specified model fits the data perfectly, Cox-Snell’s R squared might be less than 1!
