چکیده
This paper presents a new approach to the estimation of the deformation of an isotropic Gaussian random field on R2 based on dense observations of a single realization of the deformed random field. Under this framework we investigate the identification and estimation of deformations. We then present a complete methodological package—from model assumptions to algorithmic recovery of the deformation—for the class of nonstationary processes obtained by deforming isotropic Gaussian random fields.

متن کاملConsistent Estimates of Deformed Isotropic Gaussian Random Fields on the Plane
This paper proves fixed domain asymptotic results for estimating a smooth invertible transformation f :R2 → R2 when observing the deformed random field Z ◦ f on a dense grid in a bounded, simply connected domain , where Z is assumed to be an isotropic Gaussian random field on R2. The estimate f̂ is constructed on a simply connected domain U , such that U ⊂ and is defined using kernel smoothed qu...
متن کاملOn the Consistent Separation of Scale and Variance for Gaussian Random Fields by Ethan Anderes
We present fixed domain asymptotic results that establish consistent estimates of the variance and scale parameters for a Gaussian random field with a geometric anisotropic Matérn autocovariance in dimension d > 4. When d < 4 this is impossible due to the mutual absolute continuity of Matérn Gaussian random fields with different scale and variance (see Zhang [J. Amer. Statist. Assoc. 99 (2004) ...

متن کاملIsotropic Gaussian Random Fields on the Sphere: Regularity, Fast Simulation and Stochastic Partial Differential Equations
Isotropic Gaussian random fields on the sphere are characterized by Karhunen–Loève expansions with respect to the spherical harmonic functions and the angular power spectrum. The smoothness of the covariance is connected to the decay of the angular power spectrum and the relation to sample Hölder continuity and sample differentiability of the random fields is discussed. Rates of convergence of ...
