Arguments
ps
A numeric vector of length 2 giving the values
of phi and sigma^2, in that order.
khat
A numeric vector giving the nonparametric
estimate of the K function at all distances specified in
useq (see below)
useq
An increasing, equally spaced numeric vector
giving the spatial distances at which the contrast
criterion is to be evaluated.
model
A character string specifying the form of
the theoretical spatial correlation function (matches
'model' argument for CovarianceFct in the RandomFields
packages).
transform
A scalar-valued function which performs
a numerical transformation of its argument. Used for
calibration of the contrast criterion, by transforming
both parametric and nonparametric forms of the K
function.
power
A scalar used for calibration of the
contrast criterion: the power which to raise the
parametric and nonparametric forms of the K function to.
...
Additional arguments if required for
definition of the correlation function as per 'model'.
