This function is used in thetaEst to estimate the temporal correlation parameter, theta.
Usage
Cvb(xyt, spatial.intensity, N = 100, spatial.covmodel, covpars)
Arguments
xyt
object of class stppp
spatial.intensity
bivariate density estimate of lambda, an object of class im (produced from density.ppp for example)
N
number of integration points
spatial.covmodel
spatial covariance model
covpars
additional covariance parameters
Value
a function, see below.
Computes Monte carlo estimate of function C(v;beta) in Brix and Diggle 2001 pp 829 (... note later corrigendum to paper (2003) corrects the expression given in this paper)
