Ae. aegypti

3.6% (p = 0.477)

9.3% (p = 0.006)

Ae. albopictus

17.5% (p < 0.001)

14.1% (p < 0.001)

  1. Under both types of spatial cross validation, the mean absolute prediction error was derived by averaging the absolute prediction errors across all sites. The p-values were obtained based on a two-sided paired t test
