资源简介:
k: number of estimable parameters; AICc: Akaike Information Criteria adjusted for small sample sizes; ΔAICc = (AICc)–(AICc)min; w: Akaike weight.a All models were fitted with a random intercept for individual identity nested within pack identity, and a random intercept for winter of sample collection.Only candidate models with ΔAICc
k:可估计参数数量;AICc:针对小样本量校正的赤池信息准则(Akaike Information Criteria);ΔAICc = (AICc) – (AICc)min:ΔAICc 为当前模型AICc值与最小AICc值的差值;w:赤池权重(Akaike weight)。注a:所有模型均设置了嵌套于群体身份内的个体身份随机截距项,以及样本采集冬季的随机截距项。仅保留ΔAICc的候选模型
