The doubly stochastic mechanism generating the realizations of spatial log-Gaussian
Cox processes is empirically assessed in terms of generalized entropy, divergence and complexity
measures. The aim is to characterize the contribution to stochasticity from the two phases involved,
in relation to the transfer of information from the intensity field to the resulting point pattern, as
well as regarding their marginal random structure. A number of scenarios are explored regarding
the Matérn model for the covariance of the underlying log-intensity random field. Sensitivity with
respect to varying values of the model parameters, as well as of the deformation parameters involved
in the generalized informational measures, is analyzed on the basis of regular lattice partitionings.
Both a marginal global assessment based on entropy and complexity measures, and a joint local
assessment based on divergence and relative complexity measures, are addressed. A Poisson process
and a log-Gaussian Cox process with white noise intensity, the first providing an upper bound for
entropy, are considered as reference cases. Differences regarding the transfer of structural information
from the intensity field to the subsequently generated point patterns, reflected by entropy, divergence
and complexity estimates, are discussed according to the specifications considered. In particular,
the magnitude of the decrease in marginal entropy estimates between the intensity random fields
and the corresponding point patterns quantitatively discriminates the global effect of the additional
source of variability involved in the second phase of the double stochasticity [-]
