资源简介:

AIC model selection table and associated coefficients for Hammond’s flycatcher 2013 for all initial occupancy 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2013年哈蒙德霸鹟(Hammond's Flycatcher)所有初始占据模型的赤池信息准则(Akaike Information Criterion, AIC)模型选择表及配套系数。模型系数的列名采用如下标注规范:系数以parameter(covariate)形式表示,标准误以SEparameter(covariate)形式表示。参数缩写对应关系为:p代表检测概率(detection probability),psi(ψ)代表初始占据率(initial occupancy),col代表定殖/定居(colonization/settlement),ext代表灭绝/空置(extinction/vacancy)。其中Parameter(Int)指代模型截距项。"nPars"表示模型中被估计的参数数量。所有模型均依据AIC得分进行排序,该得分用于量化模型对数据的拟合优度。ΔAIC(delta)值越低,表明模型拟合效果越优。AICwt(AIC权重)用于表征当前模型在所有待测试模型中最能解释数据的概率。
