  1. Span is the percentage of data used for smoothing the model.
  2. a Optimal span obtained by using the Akaike's Information Criterion (AIC) unless otherwise noted.
  3. b Same span as for adjusted, all residences.
  4. c Number of residences contributed to the analysis by participant status.
  5. d Null hypothesis is that the map is flat.
  6. e The p-values were omitted because the maps were created using a non-optimal span.
