# What is pseudo R square?

Pseudo R2 is a measure of how well variables of the model explain some phenomenon. If we catch with our variables more than 0,5 we can form our expectation for the model, but there are other unexplained issues and then try to find other factors that can explain and test our thesis.

Consequently, what is a good pseudo R Squared?

A rule of thumb that I found to be quite helpful is that a McFadden's pseudo R-squared ranging from 0.2 to 0.4 indicates very good model fit. As such, the model mentioned above with a McFadden's pseudo R-squared of 0.192 is likely not a terrible model, at least by this metric, but it isn't particularly strong either.

Furthermore, what is nagelkerke r2? Nagelkerke's R 2 2 is an adjusted version of the Cox & Snell R-square that adjusts the scale of the statistic to cover the full range from 0 to 1. McFadden's R 2 3 is another version, based on the log-likelihood kernels for the intercept-only model and the full estimated model.

In respect to this, how do you interpret pseudo R Squared?

A pseudo R-squared only has meaning when compared to another pseudo R-squared of the same type, on the same data, predicting the same outcome. In this situation, the higher pseudo R-squared indicates which model better predicts the outcome.

What is a strong R Squared?

R-squared should accurately reflect the percentage of the dependent variable variation that the linear model explains. Your R2 should not be any higher or lower than this value. Any study that attempts to predict human behavior will tend to have R-squared values less than 50%.
