Description

Kriging correlation function, no nugget

Usage

1
corrkriging(theta, d, ret = "all")

Arguments

theta

parameters in the correlation function

d

m*n matrix with differences between given data points

ret

A string. If set to "all" or "dr", the derivative of r (dr) will be returned, else dr is NA.

Value

returns a list with two elements:

r

correlation

dr

m*n matrix with the Jacobian of r at x. It is assumed that x is given implicitly by d[i,] = x - S[i,], where S[i,] is the i'th design site.
