Econometric Analysis of the Relationship between Household Consumption Expenditures, Income, and Gross Savings in Uzbekistan (2010-2024)

This study examines the linear relationship between household consumption expenditures (Y) and the key influencing factors — household income (X1) and gross savings (X2) — in the Republic of Uzbekistan, using a multiple linear regression model. Based on data for 2010–2024, the regression equation was derived and diagnostic tests were performed using the t-Student, F-Fisher criteria, and the coefficient of determination. The results confirm that the model is statistically reliable and explains 99.8% of the variance in consumption expenditures. Household income (X1) was identified as the strongest determinant of consumption, while gross savings (X2) was found to be of secondary significance within the given sample.
