资源简介:

AIC model selection table and associated coefficients for Hammond's flycatcher 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年哈蒙德霸鹟(Hammond's flycatcher)所有检测模型对应的AIC(赤池信息准则,Akaike Information Criterion)模型选择表及关联系数。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)」,标准误则记作「SE(参数(协变量))」。参数缩写说明如下:p代表检测概率,ψ(psi)代表初始占用率,col代表定殖/定居过程,ext代表灭绝/空置过程。Parameter(Int)指代模型截距项。「nPars」表示模型中被估计的参数总数量。所有模型均依据AIC得分进行排序,该得分用于衡量模型对数据的拟合优劣程度。ΔAIC(delta)值越低,代表模型的拟合效果越优。AICwt(AIC权重)用于表示当前模型在所有已测试模型中最优解释数据的概率。
