Most of the literature on spatio-temporal covariance models proposes structures
that are positive in the whole domain. However, problems of physical, biological or
medical nature need covariance models allowing for negative values or oscillations
from positive to negative values. In this paper we propose an easy-to-implement
and interpretable class of models that admits this type of covariances. We show
particular analytical examples that may be of interest in the biometrical context [-]
