Remarks
The Wald statistical test is a test for a model parameter in which the estimated parameter θ is compared with another proposed parameter under the assumption that the difference between them will be approximately normal. There are several problems with the use of the Wald test. Please take a look on substitute tests based on the log-likelihood if possible.
