Econometrics may use standard statistical models to study economic questions, but most often they are with observational data, rather than in controlled experiments. [10] In this, the design of observational studies in econometrics is similar to the design of studies in other observational disciplines, such as astronomy, epidemiology, sociology and political science.
An econometric model then is a set of joint probability distributions to which the true joint probability distribution of the variables under study is supposed to belong. In the case in which the elements of this set can be indexed by a finite number of real-valued parameters , the model is called a parametric model ; otherwise it is a ...
Econometrics is an application of statistical methods to economic data in order to give empirical content to economic relationships. [1] More precisely, it is "the quantitative analysis of actual economic phenomena based on the concurrent development of theory and observation, related by appropriate methods of inference."
In an economic model, an exogenous variable is one whose measure is determined outside the model and is imposed on the model, and an exogenous change is a change in an exogenous variable. [1]: p. 8 [2]: p. 202 [3]: p. 8 In contrast, an endogenous variable is a variable whose measure is determined by the model. An endogenous change is a change ...
Let the model be y = f(x, z) + u. If the variable x is sequential exogenous for parameter α {\displaystyle \alpha } , and y does not cause x in the Granger sense , then the variable x is strongly/strictly exogenous for the parameter α {\displaystyle \alpha } .
Econometric models are used by economists to estimate relationships between large numbers of variables, most importantly to model national economies or the world economy. Econometric models is included in the JEL classification codes as JEL: C5
