AIC model selection table and associated coefficients for Pacific wren 2013 for all models combined. 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.

2013年太平洋鹪鹩(Pacific wren)全模型合并后的AIC模型选择表及对应系数。模型系数的列名遵循以下记法:系数项记为「参数(协变量)」,标准误项记为「SE参数(协变量)」。参数缩写定义如下:p = 检测概率(detection probability),ψ(psi)= 初始占用率(initial occupancy),col = 定殖/定居(colonization/settlement),ext = 灭绝/空置(extinction/vacancy)。Parameter(Int) 指代模型截距项。「nPars」表示模型中估计的参数数量。所有模型均按AIC得分排序,AIC得分用于衡量模型对数据的拟合优度。ΔAIC(delta)值越低,代表模型拟合效果越优。AICwt 可用于表征受试模型中,该模型为最优数据解释模型的概率。
