The truncated spline nonparametric regression method was used in this study to accommodate the complex relationship between variables without assuming a particular distribution. The results of the analysis show that all three independent variables have an effect. The results of the analysis show that the best model is obtained with four knot points, producing a minimum Generalized Cross Validation (GCV) value of 7,9580594, a minimum Mean Squared Error (MSE) value of 3.899, and a coefficient of determination (R²) of 77,96%. With a fairly high level of accuracy, this model can be used as a basis for further analysis in understanding the relationship between economic variables and the HDI. In addition, this model can be a reference in formulating more effective policies to reduce economic inequality and improve the welfare of people in the poorest areas on Sumatra Island.}, issn = {2339-2541}, pages = {480--488} doi = {10.14710/j.gauss.14.2.480-488}, url = {https://ejournal3.undip.ac.id/index.php/gaussian/article/view/51363} }
