New LASSO estimator tackles high-dimensional panel data regressions

By PulseAugur Editorial · [2 sources] ·

A new paper introduces a factor-augmented sparse-group LASSO estimator designed for high-dimensional panel data regressions. This method addresses settings with cross-sectionally dependent errors caused by common shocks. The proposed estimator integrates MIDAS aggregation with latent factors, allowing it to leverage mixed-frequency group structures in time-series data. Theoretical analysis suggests this approach can yield superior prediction and estimation performance compared to standard LASSO, particularly when dealing with cross-sectional dependence. AI
