....Matheron [310] in honor of D. G. Krige [311] a South African mining engineer who developed empirical methods for determining true ore grade distributions from distributions based on sampled ore grades [312] 313] Kriging has been studied in the context of geostatistics [312] 314] [315], cartography [316] and meteorology [317] and is closely related to interpolation by thin plate splines or radial basis functions [318] 319] In medical imaging, the technique seems to have been applied first by Stytz and Parrot [320] 321] More recent studies related to kriging in signal and ....

....will often demand much higher dimensional input spaces. The problem of the choice of x i s is one of experimental design. An important review of DACE work is Sacks et al. (1989) and for more recent work on computer experiment design see Bates et al. (1996) A good reference for geostatistics is Stein (1999). 1.3 SACCO The main focus in DACE was to predict the output (x) of the computer code at some untried input con. guration. The result is a statistical approximation to the code, that agrees with the observed outputs at the design inputs but interpolates smoothly between them to allow prediction ....

....ratio of the variance 2 i (also called the sill parameter) and the range ( 1 i ) to the 2 th i power, i = 2 i 2 i : The parameter i changes with location. The smoothness of a random eld, the parameter i in the Mat ern class, plays a critical role in interpolation problems (Stein, 1999). A number of commonly used models for the covariance structure, including spherical, exponential and Gaussian structures assume that the smoothness parameter is known a priori. The rst step in our analysis will be to estimate this parameter from the data, instead of considering it known. We ....

Following the recommendations of Stein (1999) we use covfS(x) S(x 0 )g = C (kx x 0 k) 7) where kvk = p v T v and C is member of the Matern family of covariance functions. It should be pointed out that (7) corresponds to S being isotropic, which we view as a reasonable working assumption for the application at hand. The most ....
...., where 2 x = VarfS(x)g is the variance of the process, is the range parameter and controls the distance at which covariances are effectively zero, and controls the smoothness of the resulting surface estimate. The full formulation of C is in terms of modified Bessel functions (e.g. Stein, 1999, p. 31) but the special case = 3=2 corresponds to C (r) 2 x (1 jrj= e jrj= 8) Indeed, in our analysis we work only with this sub family of the Matern covariance functions. We chose (8) because it is the simplest member of the Matern family that results in differentiable ....

....OE i are constant over the 15 domain. This is a consequence of the fact that low frequency behavior of the spectrum (small values of k k) or the higher order correlations, should have little effect on interpolation. It is possible to provide a quantitative theory supporting this point of view (Stein, 1999a) Consider f 0i to be the true spectral density of the process Z i and f 1i an incorrect one. If f 1i ( f 0i ( 1 as j j 1, then all linear predictors under the incorrect f 1i are uniformly asymptotically correct. Thus, if the goal is spatial interpolation, it is preferable to work on the spectral domain ....
