This can be accomplished in linear regression through use of a Wald test. In statistics, a random effects model, also called a variance components model, is a statistical model where the model parameters are random variables. It is a kind of hierarchical linear model, which assumes that the data being analysed are drawn from a hierarchy of different populations whose differences relate to that hierarchy. In econometrics, random effects models are used in the analysis. Instrumental Variable Identication and Estimation of Nonseparable Models, 2007, with G. Newey, Journal of Econometrics.

We especially welcome questions that are likely to be of interest to other readers. Estimating a VAR The vector autoregressive model (VAR) is actually simpler to estimate than the VEC model. It is used when there is no cointegration among the variables and it is estimated using time series that have been The rst edition of Basic Econometrics was published thirty years ago.

Estimation of any BoxCox parameters is by maximum likelihood. Box and Cox (1964) offered an example in which the data had the form of survival times but the underlying biological structure was of hazard rates, and the transformation identified this.
