Sparse plus dense MIDAS regressions and nowcasting during the COVID pandemic

no code implementations23 Jun 2023 Jad Beyhum, Jonas Striaukas

The common practice for GDP nowcasting in a data-rich environment is to employ either sparse regression using LASSO-type regularization or a dense approach based on factor models or ridge regression, which differ in the way they extract information from high-dimensional datasets.

High-Dimensional Granger Causality Tests with an Application to VIX and News

1 code implementation13 Dec 2019 Andrii Babii, Eric Ghysels, Jonas Striaukas

We establish the debiased central limit theorem for low dimensional groups of regression coefficients and study the HAC estimator of the long-run variance based on the sparse-group LASSO residuals.
