Arguments
theta
Single numeric value for the parameter
controlling the scale of temporal dependence in the
frequency of observations.
data
Object of class stppp, giving the observed
spatiotemporal data set.
ps
A numeric vector of length 2 giving fixed
values of phi and sigma^2, in that order.
Chat
A numeric vector giving the nonparametric
estimate of the temporal autocorrelation function at all
temporal lags specified by vseq.
vseq
An increasing, equally spaced numeric vector
giving the temporal distances at which the contrast
criterion is to be evaluated.
spat
A density estimate of the fixed, possibly
inhomogeneous, density of the underlying spatial trend.
An object of class 'im' (spatstat). May be unnormalised;
in which case it will be scaled to integrate to 1 over
the spatial study region.
model
A character string specifying the form of
the theoretical spatial correlation function (matches
'model' argument for CovarianceFct in the RandomFields
packages).
