shrink_estim

Shrinkage of the covariance matrix according to Schäfer and Strimmer (2005).

Classical (bottom-up and top-down), optimal combination and heuristic
point (Di Fonzo and Girolimetto, 2023 <doi:10.1016/j.ijforecast.2021.08.004>) and
probabilistic (Girolimetto et al. 2023 <doi:10.1016/j.ijforecast.2023.10.003>)
forecast reconciliation procedures for linearly constrained time series
(e.g., hierarchical or grouped time series) in cross-sectional, temporal,
or cross-temporal frameworks.
