Advanced spatio temporal modeling with geographically and temporally weighted spline regression (GTWSR) for strategic food price forecasting in Indonesia

This study proposes an advanced spatio-temporal framework to forecast strategic food commodity prices in Indonesia using Geographically and Temporally Weighted Spline Regression (GTWSR), a nonparametric extension of GTWR designed to capture nonlinear spatio temporal effects. Monthly data from the St...
