Table 2. Outputs of a backward step-wise GEE analysis with the binary sting event at Maroubra and Coogee concatenated as the response variable, in summer only.

Predictors are the lagged wind zonal and meridional components, the water temperature, wave height, rip currents estimates, the ocean currents zonal and meridional components, a seasonality variable accounting for an annual cycle peaking on the 7th of February, a “site” variable (1 for Coogee, 2 for Maroubra) and the root square of the beach attendance time-series. Only significant predictors are shown with their coefficients, 95% confidence interval, and p-value.
