Reporting coefficients listed in log-odds units, significance of test that coefficient is different from 0, and (n). For SPEI, the coefficient is determined without other covariates. For other predictors, coefficients are determined when controlling for SPEI. Data sources: 2016 survey, SPEI (droughtatlas.unl.edu). ;.
