A function to declare and also evaluate a spiked exponential covariance function. Note that the present version of lgcp only offers estimation for sigma and phi, the additional parameter 'spikevar' is treated as fixed.
SpikedExponentialCovFct(d, CovParameters, spikevar = 1)toral distance
parameters of the latent field, an object of class "CovParamaters".
the additional variance at distance 0
the spiked exponential covariance function; note that the spikevariance is currently not estimated as part of the MCMC routine, and is thus treated as a fixed parameter.
