AIC model selection table and associated coefficients for chestnut-backed chickadee 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.

本数据集包含棕背山雀(Chestnut-backed Chickadee)2013年所有合并模型的赤池信息准则(Akaike Information Criterion, AIC)模型选择表及相关系数。模型系数的列名采用如下标注规则:系数形式为「参数(协变量)」,标准误形式为「SE参数(协变量)」。参数缩写对应含义如下:p为检测概率(detection probability),ψ(psi)为初始占用率(initial occupancy),col为定殖/定居(colonization/settlement),ext为灭绝/空居(extinction/vacancy)。其中Parameter(Int)指代截距项(intercept)。「nPars」表示模型中估计的参数总数。所有模型均按AIC得分排序,该得分用于衡量模型对数据的拟合程度;ΔAIC(delta)值越低,代表模型拟合效果越优。AICwt则表示当前模型(在所有测试模型范围内)能够最优解释该数据集的概率。
