A Wald continuous random variable. As an instance of the rv_continuous class, Wald object inherits from it a collection of generic methods (see below for the full list), and completes them with details specific for this particular distribution. Notes. The probability density function for Wald is:

In statistics, the Wald test assesses constraints on statistical parameters based on the weighted distance between the unrestricted estimate and its hypothesized value under the null hypothesis, where the weight is the precision of the estimate. Intuitively, the larger this weighted distance, the less likely it is that the constraint is true. While the finite sample distributions of Wald tests are generally unknown, it has an …

I ran GEMMA with `-lmm 1` to compute Wald p-values. and I'm trying to manually compute these same p-values using the results for beta and SE in the GEMMA output (suffix .assoc.txt). For some reason, the p-values I obtain are not exactly the same as those given by GEMMA.

"Wald's book is clearly the first textbook on general relativity with a totally modern point of view; and it succeeds very well where others are only partially successful. The book includes full discussions of many problems of current interest which are not treated in any extant book, and all

You're using the Wald.test() function incorrectly (you should also mention what package the Wald.test function is in since it's not in base R). You need to supply it with the variance-covariance matrix of the coefficients and the residual degrees of freedom. These are both in the lm object but not the summary.lm object. Here's how you can get the same results using both methods:

The Wald test compares the fit of a restricted model against an unrestricted model by testing whether the restriction function, evaluated at the unrestricted maximum likelihood estimates (MLEs), is significantly different from zero.

Wald test. In statistics, the Wald test (named after Abraham Wald) assesses constraints on statistical parameters based on the weighted distance between the unrestricted estimate and its hypothesized value under the null hypothesis, where the weight is the precision of the estimate. Intuitively, the larger this weighted distance, ...
The Wald test examines a model with more parameters and assess whether restricting those parameters (generally to zero, by removing the associated variables from the model) seriously harms the fit of the model. In general, both tests should come to the same conclusion (because the Wald test, at least in theory, approximate the LR test).
The likelihood ratio (lr) test and Wald test test are commonly used to evaluate the difference between nested models. One model is considered nested in another if the first model can be generated by imposing restrictions on the parameters of the second.
Intuitively, the larger this weighted distance, the less likely it is that the constraint is true. While the finite sample distributions of Wald tests are generally unknown, it has an asymptotic χ 2 -distribution under the null hypothesis, a fact that can be used to determine statistical significance.
