The models are ranked based on AICc and presented by rank order.

The errors terms for each of the regression with autoregressive integrated moving average errors models is presented as ARIMA(p,d,q)(P,D,Q)s where p indicates the autoregressive (AR) order, d the differencing order, q the moving average (MA) order, and P, D, Q are the seasonal equivalents, and s is the seasonal period. The Akaike ΔAICci is the difference between each AICci and the minimum AICc. The weight wi represents the probability of each model given the data and the other candidate models in the set. Prediction accuracy is evaluated based on the R2 and RMSE. In addition, coefficients for each of the terms in the model in addition to the error terms are presented. Abbreviations: Rhx is relative humidity, Tmin is the minimum temperature, and Prcp is precipitation. The baseline model, which is based solely on previous confirmed cases of HPS is bold in the table.
