Short-term spatial dependence between cases.

<p>Spatial dependence between cases occurring within the same month as measured through <i>φ(d₁, d₂)</i> where <i>d₁</i> and <i>d₂</i> is the distance range between cases. The spatial range (<i>d₂−d₁</i>) was kept constant at 1 km when <i>d₂</i> was greater than 1 km. When <i>d₂</i> was less than 1 km, <i>d₁</i> was equal to zero. Estimates are plotted at the midpoint of the spatial ranges.</p
