Webb15 aug. 2024 · Pseudo-R² marks the progress between the null model and the perfect model. -468 is 6.4% of the way between -500.4 and 0, so the pseudo-R² of that model is 6.4%. 6.4% may not sound like a lot, but that’s because we’re considering how far it gets towards a perfect model. Webb24 jan. 2024 · They are not calculated to minimize variance, so the OLS approach to goodness-of-fit does not apply. However, to evaluate the goodness-of-fit of logistic models, several pseudo R-squareds have been developed. These are "pseudo" R-squareds because they look like R-squared in the sense that they are on a similar scale, ranging from 0 to 1 …
