Example of a coverage computation for an instance of the bivariate snowflake model with noise $\gamma =0.1$ and $N=1600$

For each value $s$ of the smoothing parameter, the combined significant areas for all four spatial conditions $\left(Z_1,Z_2\right)\in \{(0,0),(1,0),(0,1),(1,1)\}$ as determined by a separate run of GeoSPM are shaded in light gray. The maximum number of significant grid cells is obtained for $s=40$, highlighted in red.
