Webb27 sep. 2016 · When you set test="Rao", it gives you the p-value from a score test. And when you set either test="Chisq" or test="LRT" (they are the same), it gives you the p-value from a likelihood ratio test. The anova.glm() function does test the same null hypothesis as the Wald test in the summary() output in this case. WebbIn the 1920s, Ronald Fisher developed the theory behind the p value and Jerzy Neyman and Egon Pearson developed the theory of hypothesis testing. These distinct theories have …
