Researchers have developed LGB+, a novel boosting procedure designed to improve macroeconomic forecasting by incorporating a wider range of basis functions beyond traditional trees. This method evaluates both linear and tree-based models at each step, advancing the superior performer to enhance predictions, particularly in scenarios with strong linear dynamics or mixed linear-nonlinear signals. The approach allows for a native decomposition of forecasts into linear and nonlinear components, offering clearer insights into variable importance and historical influence. AI
