The predicted probability (derived from logistic regression) of detecting Coccidioides as a function of month and site.
Predicted probabilities are displayed as means as a function of month (A) and as individual samples as a function of site (B) (points jittered for clarity). * = months differ significantly (* = p < 0.05, ** = p < 0.01, *** = p ≤ 0.001, Tukey-adjusted pairwise contrasts). Letters (XYZ) denote groups of sites that do not significantly differ (p > 0.05, Tukey-adjusted pairwise contrasts). Total month contrasts = 66. Total site contrasts = 10. “rho squared” (ρ2) = McFadden’s pseudo r2. p = significance of full logistic regression model derived from deviance and null deviance. n = 238.
