收藏资源简介:
AIC model selection table and associated coefficients for Steller's jay 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.
本数据集包含针对2013年暗冠蓝鸦(Steller's jay)所有整合模型的赤池信息准则(AIC)模型选择表及配套模型系数。模型系数的列名采用如下命名规范:系数列格式为parameter(covariate),标准误列格式为SEparameter(covariate)。参数缩写定义如下:p代表检测概率,psi代表初始占用率,col代表拓殖/定居,ext代表灭绝/空置。Parameter(Int)指代截距项。nPars表示模型中被估计的参数总数。所有模型均依据其AIC得分进行排序,AIC得分用于衡量模型对数据的拟合优度。∆AIC(delta值)越低,表明模型的拟合效果越好。在所有被检验的模型中,最优解释数据的模型概率由AICwt(AIC权重)表征。
