Univariable multinomial analysis coefficients and odds ratios for climate predictors. Specific humidity and precipitation units were converted to g/kg from kg/kg and cm/day from mm/day, respectively, to reduce exponential power of odds ratios. Selection for inclusion in the multivariable analysis took into consideration variable effect size, significance, and literature support for inclusion.
