%description
Implements the Johansen cointegration test with Fourier-type smooth
nonlinear deterministic trends restricted to cointegrating relations, as
developed by Kurita and Shintani (2025)
<doi:10.1080/07474938.2025.2530640>. Six model variants are supported: CNR
(constant plus nonlinear, restricted in the cointegrating space), LNR
(linear plus nonlinear, restricted), CNU (constant restricted, nonlinear
unrestricted), LNU (linear restricted, nonlinear unrestricted), plus the
standard constant- and linear-trend restricted Johansen models. The
package also bundles the feasible generalised least squares (FGLS) Wald
test of Perron, Shintani and Yabu (2017) <doi:10.1111/obes.12169> used as
a frequency-selection pre-step, together with bundled critical-value
tables, a vectorised simulator for the limiting distribution,
publication-quality table exports (LaTeX and HTML) and 'ggplot2' figures
matching those of the paper.
