WebI run a Multinomial Logistic Regression analysis and the model fit is not significant, all the variables in the likelihood test are also non-significant. However, there are one or two … 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.
