WebTo perform a likelihood ratio test, one must estimate both of the models one wishes to compare. The advantage of the Wald test is that it approximates the LR test but require that only one model be estimated.

Web(1) The Chow test is for a change in the coefficients of a regression model at a known time. If you don't know at which point in time the (hypothesized) structural change occurs, don't use a Chow test. WebThis test is based on the inverse of the information matrix and is therefore based on a quadratic approximation to the likelihood function; see[R] test. A more precise test would be to reﬁt the model, applying the proposed constraints, and then calculate the likelihood-ratio test. We ﬁrst save the current model:. estimates store full
