Model estimates of the effects of weather and socioeconomic development on dengue across Mexico.

Values in bold font were significant at the 0.001 level. edf = effective degrees of freedom of the smooth function terms (edf>1 indicate nonlinear relationships); F-value is an approximate F-test as in [21], maximum number of spline basis for the meteorological terms = 5. SE = approximate asymptotic standard error; GCV = Generalized Cross Validation. Estimation was performed via Penalized Iteratively Reweighted Least Squares (P-IRLS) and GCV score minimization by outer iteration.
