AIC model selection table and associated coefficients for hermit thrush 2012 for all detection models. Column names for the model coefficients use the following notation: coefficient = parameter(covariate) and standard error = SEparameter(covariate). Parameter abbreviations are p = detection probability, psi = initial occupancy, col = colonization/settlement, ext = extinction/vacancy. Parameter(Int) refers to the intercept. ‘nPars’ is the number of parameters estimated in the model. Each model is ranked by its AIC score, which represents how well the model fits the data. A lower ∆AIC (delta) value is indicative of a better model. The probability that the model (of the models tested) would best explain the data is indicated by AICwt.

本数据集涵盖2012年隐夜鸫(Hermit Thrush)所有检测模型的赤池信息准则(Akaike Information Criterion,AIC)模型选择表与对应系数。模型系数的列名采用如下标注规则:系数记为 coefficient = parameter(covariate),标准误误记为 standard error = SEparameter(covariate)。参数缩写规则如下:p代表检测概率(detection probability),psi代表初始占据率(initial occupancy),col代表拓殖/定居(colonization/settlement),ext代表灭绝/空置(extinction/vacancy)。Parameter(Int)指代截距项。nPars表示模型中被估计的参数总数。所有模型均按其AIC得分排序,该得分用于量化模型对数据的拟合程度;ΔAIC(Δ)值越低,代表模型拟合效果越优。AIC权重(AICwt)用于表示当前模型在所测试的全部模型集中最优解释数据的概率。
