CORRELATION-REGRESSION RELATIONSHIPS IN ANALYSIS OF THE ECONOMY OF THE REPUBLIC OF SOUTH AFRICA

In this study, a correlation-regression analysis was conducted based on the main macroeconomic indicators of the national economy of the Republic of South Africa (ZAR). In the study, the factors affecting GDP were evaluated in statistical correlation based on World Bank data. Using the correlation matrix, the level of linear correlation was determined, and a model was developed to explain the dynamics of GDP through multivariate regression. The results show that the services sector and exports are the main drivers of South Africa's GDP, while industry and agriculture are stable structural factors.
