Negative log likelihood model results, excluding research vessel-only intervals.

Results of the negative log likelihood model (excluding research vessel-only intervals, n = 30). Model parameters are the vessel characteristics that contribute to received noise. The model that best fit the data was model 2. However, models with additional parameters also had an adequate amount of weight but due to the nature of AICc, could represent uninformative parameters.

负对数似然模型（negative log likelihood model）的结果（已剔除仅科研船（research vessel）作业时段的数据，样本量n=30）。模型参数为与接收噪声相关的船舶特性参数。拟合效果最优的模型为模型2。不过，带有额外参数的模型同样拥有可观的模型权重，但鉴于校正赤池信息准则（AICc）的特性，这类模型可能包含无信息参数。
