✦ Synopsis

In this paper, a class of product-sum covariance models has been introduced for estimating and modeling space-time correlation structures. It is shown how the coe cients of this class of models are related to the global sill and "partial" spatial and temporal sills; moreover, some constraints on these sills have been given in order to assure positive deÿniteness of the product-sum covariance model. A brief comparative study with some other classes of spatial-temporal covariance models has been pointed out.

A generalized model for time series count data with serially correlated random e ects is introduced to establish robust inference procedures. Observations are taken at possibly unequally spaced time intervals and random e ects are assumed to have a stationary ergodic continuous time ÿrst-order autor
