%description
Offers a set of tools for visualizing and analyzing size and power
properties of the test for equal predictive accuracy, the Diebold-Mariano
test that is based on heteroskedasticity and autocorrelation-robust (HAR)
inference. A typical HAR inference is involved with non-parametric
estimation of the long-run variance, and one of its tuning parameters, the
truncation parameter, trades off a size and power. Lazarus, Lewis, and
Stock (2021)<doi:10.3982/ECTA15404> theoretically characterize the
size-power frontier for the Gaussian multivariate location model.
'ForeComp' computes and visualizes the finite-sample size-power frontier
of the Diebold-Mariano test based on fixed-b asymptotics together with the
Bartlett kernel. To compute the finite-sample size and power, it works
with the best approximating ARMA process to the given dataset. It informs
the user how their choice of the truncation parameter performs and how
robust the testing outcomes are.
