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

<p>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 ΔAICc_i is the difference between each AICc_i and the minimum AICc. The weight <i>w_i</i> 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 <b>bold</b> in the table.
