Fig. 6. Demography, housing construction, and climate affect model predictive capacity for vectors.

Factors that influence the predictability of vector dynamics include (a) proportion of the population under five years of age, (b) proportion of houses with piped water, (c) mean temperature and (d) proportion of houses made with cement (walls and/or floors). Points indicate the pairwise correlation value for a single site (colors) with different symbols for Ecuador (circles) and Kenya (triangles). Each plot also shows the linear regression lines and associated statistics (R² = coefficient of determination; P value = probability of two-sided hypothesis test).
