Tests on properties of space-time covariance functions.
Tests on symmetry, separability and for assessing
different forms of non-separability are available. Moreover tests on
some classes of covariance functions, such that the classes of
product-sum models, Gneiting models and integrated product models have
been provided. It is the companion R package to the papers of
Cappello, C., De Iaco, S., Posa, D., 2018, Testing the type of non-separability
and some classes of space-time covariance function models
