资源简介:

AIC model selection table and associated coefficients for Pacific wren 2012 for dynamic models (colonization and extinction). 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.

本数据集收录了2012年太平洋鹪鹩(Pacific wren)定殖与灭绝动态模型的赤池信息准则(AIC)模型选择表及对应系数。模型系数的列名遵循如下标注规则:系数形式为「参数(协变量)」,标准误形式为「SE参数(协变量)」。参数缩写对应关系如下:p代表检测概率,ψ(psi)代表初始占用率,col代表定殖/定居,ext代表灭绝/空置。Parameter(Int)指代模型截距项。「nPars」表示模型中被估计的参数总数。所有模型均依据AIC分值进行排序,该分值用于量化模型对数据的拟合优度。ΔAIC(delta)值越低,说明模型的拟合效果越佳。在所有待测试模型中,该模型最优解释数据的概率由AICwt(AIC权重)给出。
