Figure 4.

Heatplot of the frequency of the maximum likelihood estimates for $10,000$ data sets, assuming independent sites with $k=100,$ $\psi =0.3,$ $\rho =10,$ and θ (Equation 45) with $s=10,000.$ Counts increase from blue to red with gray squares showing zero counts. The green square shows the true ψ and ρ. The black star shows the median (and mean) of the maximum likelihood estimates $\psi$ and $\widehat{\rho }.$
