Régression linéaire multiple : démarche et interprétation

This document focuses on the application of multiple linear regression analysis using EViews 10.0 to study a macroeconomic model. The primary objective is to establish a linear relationship between variables such as GDP, DCF, FBCF, RNB, and TINTER. Key statistical parameters and the correlation matrix are calculated to assess multicollinearity. Diagnostic tests for autocorrelation and heteroscedasticity are performed, identifying significant issues with autocorrelation and heteroscedasticity. The statistical significance of the model's parameters is evaluated, and the results suggest that c...
