Relating to the application of statistical and mathematical methods to economic data and problems.
The econometric model helped predict future economic trends based on past data.
Econometric is formed from "economy" (from Greek "oikonomia", meaning household management or administration) and "metric" (from Greek "metron", meaning measure). The word refers to the measurement and analysis of economic data.
