The Internal Consistency of Models in Geostatisticso a question concerning the consistency of these models: for a given system of bivariate distributions, does a random function which could be compatible with this system, really exist? Going further, which class of covariances is compatible with a given univariate distribution? The condition under w作者: 未開(kāi)化 時(shí)間: 2025-3-22 02:42

A Bayesian Approach to Krigingbe known, the latter assumes nothing about the parameters involved in the expected function. The Bayesian approach allows the user to specify prior knowledge about model parameters as a qualified guess with uncertainties. This may be done in cases where the parameters have physical meaning.

A brief discussion of the more common techniques for simulating fractals demonstrates their limited usefulness compared to geostatistical techniques.
