^a Optimal span obtained by using the Akaike's Information Criterion (AIC) unless otherwise noted.
^b Same span as for all residences.
^c Null hypothesis is that the map is flat. S-Plus p-value is only approximate.
^d The p-values were omitted because the maps were created using a non-optimal span.
