Abstract
This paper introduces some X2 random functions, which are not homogeneous (stationary) in general, but contain the stationary case as a special case, and whose correlation structures are nonparametric and flexible so that many parametric forms can be specified. The mean square differentiability of such X2 random function is discussed.We also make the comparison of two X2 random functions through their finite-dimensional Laplace transforms. © 2009 IEEE.
