The final model was highly significant, with a R 2 value of 0.89 ( F (5) = 27.9, P < 0.001), and the model formulated was: Sand fly density = 2.9 × THF + 1.5 × TW + 2.1 × DS + 1.3 × ISV + 1.7 × IRSs - 13.0 TR was deselected in the final model for its least significance ( P = 0.46) with other explanatory variables.
