%description
Vector autoregressive (VAR) model is a fundamental and effective approach
for multivariate time series analysis. Shrinkage estimation methods can be
applied to high-dimensional VAR models with dimensionality greater than
the number of observations, contrary to the standard ordinary least
squares method. This package is an integrative package delivering
nonparametric, parametric, and semiparametric methods in a unified and
consistent manner, such as the multivariate ridge regression in Golub,
Heath, and Wahba (1979) <doi:10.2307/1268518>, a James-Stein type
nonparametric shrinkage method in Opgen-Rhein and Strimmer (2007)
<doi:10.1186/1471-2105-8-S2-S3>, and Bayesian estimation methods using
noninformative and informative priors in Lee, Choi, and S.-H. Kim (2016)
<doi:10.1016/j.csda.2016.03.007> and Ni and Sun (2005)
<doi:10.1198/073500104000000622>.
