Hazard Periods Sample Clauses

Hazard Periods. Univariate analyses of each predictor variable (average precipitation over two weeks, average maximum temperature over five weeks, and average minimum temperature over five weeks) evaluated in three separate models show that no variable is significantly associated with an outbreak individually (Table 4). When average precipitation for the two-week hazard period, average maximum temperature for the five-week hazard period, and average minimum temperature for the five-week hazard period were all included in the same model, the likelihood ratio for the model was not significant (p=0.165). However, average minimum temperature was significant in the model (OR=1.033; 95% CI: 1.003-1.063) (Table 5, Figure 2) (Table 5, Figure 2). To analyze the suitability of including both average maximum temperature and average minimum temperature in the same model, partial correlation was calculated between the average maximum temperature for the five-week hazard period and the average minimum temperature for the five-week hazard period, controlling for strata. The two variables are strongly correlated r(245)=0.834, p <0.001 (Figure 3). Average maximum temperature and average minimum temperature were subsequently not included in the models simultaneously.
