Despite the clear success of forecast combination in many economic environments, several important issues remain incompletely resolved. The issues relate to the selection of the set of forecasts to combine, and whether some form of additional regularization (e.g., shrinkage) is desirable.

Rather than the undirected relationships, a number of practical problems concern much about …

However, it is known that the LASSO selects too many noisy variables. In this paper, we propose a new estimator, the moderately clipped LASSO (MCL), that deletes noisy variables successively without sacrificing prediction accuracy much. Various numerical studies are done to illustrate superiority of the MCL over other competitors.A kernel reweighted group lasso method is proposed, which overcomes the limitations of sample scarcity and transforms the problem of Granger causal structural learning into a group variable selection problem. The asymptotic consistency of the proposed algorithm is proved.📈 Ordered Homogeneity Pursuit Lasso for Group Variable Selection - GitHub - nanxstats/OHPL: 📈 Ordered Homogeneity Pursuit Lasso for Group Variable SelectionThe hybrid methodology adopts the adaptive LASSO regularization to simultaneously reduce predictor dimension and obtain quantile forecasts.
