为什么 glmulti R 包中的函数在 lmer 拟合(线性混合模型)和 gls 拟合模型(lme 包)上不能很好地工作:
A. 提取模型平均系数?它的 coef 函数不起作用。
我在 lmer 拟合模型(即混合模型)上使用了 glmulti R 包并运行了模型选择。但是我没有进行模型平均,因为即使我应用了这里提到的包装器 getfit() 函数glmulti 和 liner 混合模型,coef 函数也不起作用
B. 它的 level=2 选择,即专用于在 glmulti 对象上包含成对交互的部分?它有时会起作用,在另一种情况下会失败。例如,当它失败时我收到此错误消息。我选择了不同的方法=“h”,“g”,“d”来查看故障是否与计算能力有关,但没有一个选择有效。“.jnew("glmulti/ModelGenerator", y, .jarray(xc), .jarray(xq), : java.lang.ArrayIndexOutOfBoundsException: 10 中的错误:”另一个问题是,一旦我在新的glmulti,那些工作良好的以前的作品将不再工作。
C. 如果我使用 MuMIn 包中的模型平均函数并将我的推断基于其输出,会产生多大的差异?我的担忧来自 glmulti 包的作者对 MuMIn 包的批评。他们说“*MuMIn 可以处理包含交互的公式,但它将交互视为标准变量,这引发了几个问题”,请参阅第 4 页的倒数第二段http://www.jstatsoft.org/v34/i12/paper。
非常感谢您的帮助 :)
感谢 Ben 的快速回复和建议。这是我的数据。Block 和 Composition 用作随机效应因子,六个变量(TShann、Alt、Slope、CPT、MAT 和 MARF)用作固定效应因子(协变量)。我想研究这六个变量对收益率的主要和成对交互影响。
