%description
The 'Greymodels' Shiny app is an interactive interface for statistical
modelling and forecasting using grey-based models. It covers several
state-of-the-art univariate and multivariate grey models. A user friendly
interface allows users to easily compare the performance of different
models for prediction and among others, visualize graphical plots of
predicted values within user chosen confidence intervals. Chang, C. (2019)
