### Jan Tinbergen

JanTinbergenJ. Tinbergen
Jan Tinbergen is considered by many to be one of the founding fathers of econometrics.
He is widely considered to be one of the most influential economists of the 20th century and one of the founding fathers of econometrics.

### Ragnar Frisch

Ragnar Anton Kittil Frisch
Ragnar Frisch is credited with coining the term in the sense in which it is used today.
He is known for being one of the founders of the discipline of econometrics, and for coining the widely used term pair macroeconomics/microeconomics in 1933.

### Econometric model

econometric modelingeconometric modelseconometric
Applied econometrics uses theoretical econometrics and real-world data for assessing economic theories, developing econometric models, analysing economic history, and forecasting.
Econometric models are statistical models used in econometrics.

### Economic history

economic historianeconomiceconomic historians
Applied econometrics uses theoretical econometrics and real-world data for assessing economic theories, developing econometric models, analysing economic history, and forecasting.
The quantitative—in this case, econometric—study of economic history is also known as cliometrics.

### Generalized method of moments

GMM
When these assumptions are violated or other statistical properties are desired, other estimation techniques such as maximum likelihood estimation, generalized method of moments, or generalized least squares are used.
In econometrics and statistics, the generalized method of moments (GMM) is a generic method for estimating parameters in statistical models.

### Economic data

Dataeconomic statisticsGeneral
Applied econometrics uses theoretical econometrics and real-world data for assessing economic theories, developing econometric models, analysing economic history, and forecasting.
Economic data provide an empirical basis for economic research, whether descriptive or econometric.

### Ordinary least squares

OLSleast squaresOrdinary least squares regression
Ordinary least squares (OLS) is often used for estimation since it provides the BLUE or "best linear unbiased estimator" (where "best" means most efficient, unbiased estimator) given the Gauss-Markov assumptions.
OLS is used in fields as diverse as economics (econometrics), data science, political science, psychology and engineering (control theory and signal processing).

### Parameter identification problem

identificationidentification problemidentified
Consequently, the field of econometrics has developed methods for identification and estimation of simultaneous-equation models.
In statistics and econometrics, the parameter identification problem is the inability in principle to identify a best estimate of the value(s) of one or more parameters in a regression.

### Simultaneous equations model

Consequently, the field of econometrics has developed methods for identification and estimation of simultaneous-equation models.
They are often used in econometrics.

### Polynomial least squares

The variance in a prediction of the dependent variable (unemployment) as a function of the independent variable (GDP growth) is given in polynomial least squares.
Polynomial least squares has applications in radar trackers, estimation theory, signal processing, statistics, and econometrics.

### Journal of Econometrics

The main journals that publish work in econometrics are Econometrica, the Journal of Econometrics, the Review of Economics and Statistics, Econometric Theory, the Journal of Applied Econometrics, Econometric Reviews, the Econometrics Journal, Applied Econometrics and International Development, and the Journal of Business & Economic Statistics.
The Journal of Econometrics is a scholarly journal in econometrics.

### Supply and demand

demandsupplylaw of supply and demand
Economics often analyses systems of equations and inequalities, such as supply and demand hypothesized to be in equilibrium.
This can be done with simultaneous-equation methods of estimation in econometrics.

### Regression analysis

regressionmultiple regressionregression model
One of the fundamental statistical methods used by econometricians is regression analysis.
The subfield of econometrics is largely focused on developing techniques that allow researchers to make reasonable real-world conclusions in real-world settings, where classical assumptions do not hold exactly.

### Choice modelling

stated preferencechoice modelchoice models
Indeed many alternative models exist in econometrics, marketing, sociometrics and other fields, including utility maximization, optimization applied to consumer theory, and a plethora of other identification strategies which may be more or less accurate depending on the data, sample, hypothesis and the particular decision being modelled.

### Edward E. Leamer

Edward Leamer
Regarding the plurality of models compatible with observational data-sets, Edward Leamer urged that "professionals ... properly withhold belief until an inference can be shown to be adequately insensitive to the choice of assumptions".
Leamer is the author of 4 books and over 100 articles on a range of subjects especially including applied econometrics and quantitative international economics.

### Financial econometrics

financial econometric
It differs from other forms of econometrics because the emphasis is usually on analyzing the prices of financial assets traded at competitive, liquid markets.

### Natural experiment

natural experimentsnaturalexperimental variable
Econometricians often seek illuminating natural experiments in the absence of evidence from controlled experiments.
Using statistical methods developed in econometrics, Angrist capitalized on the approximate random assignment of the Vietnam War draft lottery, and used it as an instrumental variable associated with eligibility (or non-eligibility) for military service.
