This binomial data-set was simulated by generating a zero-mean Gaussian process over a 30 by 30 grid covering the unit square. The parameters used in the simulation are sigma2=1, phi=0.15 and kappa=2. The nugget effect was not included, hence tau2=0.
The variables are as follows:
y binomial observations.
units.m binomial denominators.
x1 horizontal coordinates.
x2 vertical coordinates.
S simulated values of the Gaussian process.
