In econometrics, as in statistics in general, it is presupposed that the quantities being analyzed can be treated as random variables.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.
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.
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."

Econometric Theory is an economics journal specialising in econometrics, published by Cambridge Journals. [2] Its current editor is Peter Phillips. [3] It is one of the main econometrics journals. [4] The journal was founded against a backdrop of strong growth in econometrics research in 1985. [4]
[2] In that case, the GARCH ( p , q ) model (where p is the order of the GARCH terms σ 2 {\displaystyle ~\sigma ^{2}} and q is the order of the ARCH terms ϵ 2 {\displaystyle ~\epsilon ^{2}} ), following the notation of the original paper, is given by
In econometrics, statistical inferences may be erroneous if, in addition to the observed variables under study, there exist other relevant variables that are unobserved, but correlated with the observed variables; dependent and independent variables .
Applied economics is the application of economic theory and econometrics in specific settings. As one of the two sets of fields of economics (the other set being the core), [1] it is typically characterized by the application of the core, i.e. economic theory and econometrics to address practical issues in a range of fields including demographic economics, labour economics, business economics ...
