WebAdding region (which has three levels, and requires two dummy variables) to the NULL model causes a drop in deviance of 21.597, corresponding to 54-1-2 degrees of freedom and a resulting (residual) deviance of 83.135. The drop in deviance test allows to test whether the model term region is significant. WebThe notation used for the test statistic is typically G2 G 2 = deviance (reduced) – deviance (full). This test procedure is analagous to the general linear F test procedure for multiple linear regression. However, note that …

Web1. Deviance plays a role in everyday life by setting boundaries between what is seen as acceptable and unacceptable behavior. These boundaries can be seen in laws, norms, regulations, and cultural values. This chapter's hypotheses might be used to help explain why some behaviors might be regarded as abnormal.
