Linear system modelling is structured in 10 stages from the general to the specific. The dynamic statistical system is the maintained model, defined by the variables of interest, their distributions, whether they are modelled or non‐modelled, and their lag polynomials. An econometric model is a (possibly) simultaneous‐equations entity, which is intended to isolate autonomous, parsimonious relationships based on economic theory. That model must adequately characterize the data evidence and account for the results in the congruent statistical system. Model formulation, identification, estimation (using an estimator generating equation), encompassing, and evaluation are considered.

Keywords: encompassing; identification; linear system modelling; model evaluation; simultaneous equations
