%description
Functions implementing multivariate state space models for purposes of
time series analysis and forecasting. The focus of the package is on
multivariate models, such as Vector Exponential Smoothing, Vector ETS
(Error-Trend-Seasonal model) etc. It currently includes Vector Exponential
Smoothing (VES, de Silva et al., 2010, <doi:10.1177/1471082X0901000401>),
Vector ETS and simulation function for VES.
