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 significant p-values in the coefficients table. Removing variables doesn't improve the model, and the only significant p-values actually become non-significant ... WebFirst, we need to choose the level of our outcome that we wish to use as our baseline and specify this in the relevel function. Then, we run our model using multinom . The multinom package does not include p-value calculation for the regression coefficients, so we calculate p-values using Wald tests (here z-tests). how to start your own blog site
