WebJan 5, 2024 · The next table of interest is titled Testing Global Null Hypothesis: BETA=0. From this table we can see the Likelihood Ratio Chi-square value of 13.4620 with a corresponding p-value of 0.0012. Since this p-value is less than .05, this tells us that the logistic regression model as a whole is statistically significant. WebTesting a single logistic regression coeﬃcient in R To test a single logistic regression coeﬃcient, we will use the Wald test, βˆ j −β j0 seˆ(βˆ) ∼ N(0,1), where seˆ(βˆ) is calculated by taking the inverse of the estimated information matrix. This value is given to you in the R output for β j0 = 0. As in linear regression ...
