"WebA statistically significant coefficient or model fit doesn’t really tell you whether the model fits the data well either. Its like with linear regression, you could have something really nonlinear like y=x 3 and if you fit a linear function to the data, the coefficient/model will still be significant, but the fit is not good. Same applies to logistic. " - Bootstrapping logistic regression
