Webb23 juli 2024 · For pseudo R2 calculation, you need the log likelihood or deviance of the null model. In your panel glm with model = "within" above, it is not possible to fit a null model. So you cannot calculate pseudo R2. If you use model = … Webb8 feb. 2014 · McFadden’s pseudo-R squared Logistic regression models are fitted using the method of maximum likelihood – i.e. the parameter estimates are those values which maximize the likelihood of the data which have been observed. McFadden’s R squared measure is defined as

I haven’t done this for a zero-inflated model like yours, but even for a logistic regression, there are many options. // To answer which formula you want, consider why you want an R 2 -style statistic.
WebbHere are two sites that discuss the different pseudo-R2s, Nagelkerke's being one of them: first, second. In short, Nagelkerke's R2 is based on the log-likelihood and is a type of scoring rule (a logarithmic one). It can be used as an overall performance measure of the model. This paper by Steyerberg et al. (2010) explains this really well imo.
