WebThe test. In the Wald test, the null hypothesis is rejected if where is a pre-determined critical value . The size of the test can be approximated by its asymptotic value where is the distribution function of a Chi-square random variable with degrees of freedom. The critical value is chosen so as to achieve a pre-determined size, as follows: WebBecause the Wald statistic is asymptotically distributed as a standard normal distribution, we can use the z -score to calculate the p -value. When we, in addition to the coefficients, …

WebWald test gives different answers to same question depending on how the question is framed. e.g.) Let R is the parameter under test. Suppose Wald Test verifies if R=1. Then the test gives different results for R=1 and log R=0. Hence, this concludes the definition of Wald Test along with its overview.
