Question

Hi,

What does the Nagelkerke R-square value mean? Additionally, what are the calues in the equation table?

Thanks!

Answer 1

To evaluate the goodness of fit of the logistic regression model, calculating Nagelkerke's R squared from the result of glm(). The Nagelkerke's R squared means the power of explanation of the model.

The Negelkerke R squared value is 0.105.
