WebThe full model has two parameters, the intercept and the effect of Ad_Type, and a deviance of 249.73. To calculate the likelihood ratio test statistic, we take the difference in deviances and compare it to a chi-squared distribution with degrees of freedom equal to the difference in parameters between the two models (which is 1 in this case). WebThe likelihood-ratio chi-square statistic (G 2) is based on the ratio of the observed to the expected frequencies. Interpretation. Use the chi-square statistics to test whether the variables are associated. In these results, both the chi-square statistics are very similar. Use the p-values to evaluate the significance of the chi-square statistics.
