摘要：

By extending the product and product-sum space-time covariance models, new families are generated as integrated products and product-sums. These include nonintegrable space-time covariance models not obtainable by the Cressie-Huang representation. It is shown how to fit the spatial and temporal components of the models as well as the probability density function. The methods are illustrated by a case study.
