Quizplus · Accepted Answer

The Wald statistic is used to test the significance of a predictor variable in a logistic regression model. It measures the extent to which the coefficient for a variable differs from its expected value under the null hypothesis (i.e., that the variable has no effect on the outcome). A high Wald statistic indicates that the variable is a significant predictor of the outcome.
