Automated Econometrics

An approach in empirical econometrics where model evaluation and selection is performed by a computerized algorithm.

In one sentence

Automated econometrics uses computerized algorithms to select, estimate, and validate econometric models (for example, specifications and variables) with the goal of improving robustness and reducing ad hoc researcher choices.

Model selection by information criteria (example)

A common automated choice is to minimize an information criterion such as BIC:

[ BIC = -2\ln \hat L + k\ln n ]

where $\hat L$ is the maximized likelihood, $k$ is the number of parameters, and $n$ is sample size.

Background

Automated econometrics refers to an advanced application within the field of econometrics where model evaluation and selection are executed by computer algorithms that follow predefined decision rules. This approach essentially automates the otherwise manual process of econometric modeling, making it potential labor-saving and improving consistency in modeling.

Historical Context

The increasing complexity of econometric models and the advent of advanced computer technologies have driven the development and adoption of automated econometrics. The efficiency of algorithms, including their ability to process large datasets, has significantly influenced how econometric analysis can be conducted in contemporary settings.

Definitions and Concepts

Automated econometrics involves using algorithms to analyze data and develop econometric models without continuous human supervision. The procedure often mirrors the general-to-specific approach in which statistically insignificant variables are systematically eliminated from the model in successive estimation rounds until only significant variables remain.

  1. Econometric Modeling: The practice of building statistical models to test hypotheses or forecast future trends using economic data.
  2. General-to-Specific Modeling: A procedure for model selection in econometrics which begins with a general model and systematically eliminates statistically insignificant variables.
  3. Algorithmic Decision Rules: Predefined rules and criteria that guide the functioning of an algorithm during the automated model selection process.
