报告简介：

In recent years, a number of classes of new multivariate randomfields have been constructedby using the approaches of covariance matrices, variogram matrices, the convolution method,spectral representations, or systems of stochastic partial differential equations (SPDEs), andhave been applied for modeling multivariate spatial data. However, the theoretical developmentof parameter estimation, prediction, and extreme values for multivariate randomfields is stillunder-developed and the range of their applications is growing constantly.

In this talk, we provide an overview on several classes of multivariate Gaussian randomfields including multivariate Matern Gaussianfields, operator fractional Brownian motion,and matrix-valued Gaussian randomfields, and some recent results on estimation and prediction of bivariate Gaussian randomfields. These results illustrate explicitly the effects of thedependence structures among the coordinate processes on statistical analysis of multivariateGaussian randomfields.
