aWTD, water table depth; the probability of SLEV transmission incidence is represented as a function of single time lags of weekly averaged modeled WTD. Whole model goodness-of-fit was assessed by log-likelihood ratio and the pseudo r-squared (uncertainty) coefficient. Individual parameter estimates were made by Wald’s chi-square test.
