Table 2. Coefficients, their standard errors (SE), t-values and significance of the terms in the best GAMLSS-model explaining the mean proportion of time spent at 0-1m by shark A.

The factor levels ‘off shelf’ and ‘time bin’ 1 (00:00–06:00) are the baseline values in the model and are included in the intercept. Time bin 2 = 06:00–12:00, 3 = 12:00–18:00 and 4 = 18:00–24:00.
