%description
The 'midasml' package implements estimation and prediction methods for
high-dimensional mixed-frequency (MIDAS) time-series and panel data
regression models. The regularized MIDAS models are estimated using
orthogonal (e.g. Legendre) polynomials and sparse-group LASSO (sg-LASSO)
estimator. For more information on the 'midasml' approach see Babii,
Ghysels, and Striaukas (2021, JBES forthcoming)
<doi:10.1080/07350015.2021.1899933>. The package is equipped with the fast
implementation of the sg-LASSO estimator by means of proximal block
coordinate descent. High-dimensional mixed frequency time-series data can
also be easily manipulated with functions provided in the package.
