Phi.varshrinkest

An object of class 'varshrinkest',
generated by <code>VARshrink()</code>.

An integer specifying the number of moving error
coefficient matrices to be calculated.

nstep

Returns the estimated coefficient matrices of the moving average
representation of a stable VAR(p), of an SVAR as an array or a converted
VECM to VAR.
This is a modification of vars::Phi() for the class "varshrinkest".

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>.
