Abstract
The econometric model means a lot of numerical relations that enables simplified representation of the economic process subject to study. Current models often involves more than ten relations (equations).
The validity of a model is tested by comparing the results with statistical observations. In order to study an economic phenomena, he is represented through a variable behavior. This economic variable depends on other variables of which is linked through mathematical relationships.
The regression analysis is a statistical technique based on the identification of two variables and is used to relate variables.
Key words: econometric model, simple linear regression, evolution, variables, analysis, performance, estimation.
