What is a good pseudo R Squared for logistic regression?
A rule of thumb that I found to be quite helpful is that a McFadden’s pseudo R2 ranging from 0.2 to 0.4 indicates very good model fit.
How do you interpret pseudo R2?
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.
How do you interpret R Squared in logistic regression?
R-squared is the percentage of the dependent variable variation that a linear model explains. 0% represents a model that does not explain any of the variation in the response variable around its mean. The mean of the dependent variable predicts the dependent variable as well as the regression model.
What is a good pseudo R squared value?
All Answers (5) McFadden’s pseudo R-squared value between of 0.2 to 0.4 indicates excellent fit.

McFadden’s pseudo R-squared value between of 0.2 to 0.4 indicates excellent fit.
How is pseudo R Squared calculated?
Technically, R2 cannot be computed the same way in logistic regression as it is in OLS regression. The pseudo-R2, in logistic regression, is defined as 1−L1L0, where L0 represents the log likelihood for the “constant-only” model and L1 is the log likelihood for the full model with constant and predictors.
Is r2 only for linear regression?
R-squared seems like a very intuitive way to assess the goodness-of-fit for a regression model. Unfortunately, the two just don’t go together. R-squared is invalid for nonlinear regression. Consequently, it’s important that you understand why you should not trust R-squared for models that are not linear.
Can you use r-squared for logistic regression?
R squared is a useful metric for multiple linear regression, but does not have the same meaning in logistic regression. Instead, the primary use for these pseudo R squared values is for comparing multiple models fit to the same dataset.
