Query: Extrapolation of Stationary Random Fields   We introduce basic statistical methods for the extrapolation of stationary
random fields. For square integrable fields, we set out basics of the kriging
extrapolation techniques. For (non--Gaussian) stable fields, which are known to
be heavy tailed, we describe further extrapolation methods and discuss their
properties. Two of them can be seen as direct generalizations of kriging.
