Table 3 Analysis of deviance of covariates associated with the household density of Anopheles mosquitoes

From: Temporal and micro-spatial heterogeneity in the distribution of Anopheles vectors of malaria along the Kenyan coast

Covariate DFa Speciesb ∆Devc,d P- valued,e
Rainfallf 5 A. gambiae 80 < 0.001

  1. aDegrees of freedom.
  2. bModels fitted separately to species-specific counts per household.
  3. cDifference between the (residual) deviance of the model with all covariates and the model without the covariate in question [46].
  4. dRounded to 2 significant figures.
  5. eCalculated assuming that, under the null hypothesis (of no statistically significant association between the covariate and the numbers of mosquitoes per household), ∆Dev is χ2 distributed with the indicated degrees of freedom [71].
  6. fIncluded as a 4th order polynomial distributed lag term yielding 5 degrees of freedom.
