Using the linear regression model in order to analyse the correlation between the Gross Domestic Product and the household effective individual final consumption

This article aims to review the changes in gross domestic product compared to the progress of the household effective individual final consumption for the 1995-2015 period. By using a series of online data published by the National Institute of Statistics, we will analyse if there is a dependency relationship between the two variables and if so, we will also study the dependence type. By using the statistical-econometric model of simple linear regression, we will notice how a variable y, called dependent variable, can be described using another variable x, called independent variable.
