我在 R 中运行一个混合效果模型,我想知道是否有代码我可以运行来获得对比对比,以进行事后测试的交互。
答:即。我目前正在运行的 tukey 测试是这样的:
有 2 个区域(ML 和 HG)和 3 个处理(Low_control、Frog 和 High_control)。
L.S <- pairs(lsmeans(juvweightmodelfeb6th, ~ Region*Treatment_three))
test(L.S, adjust = "tukey")
B. 这让我在输出中得到了这些比较:
HG,Low_control - ML,Low_control
HG,Low_control - HG,Frog
HG,Low_control - ML,Frog
HG,Low_control - HG,High_control
HG,Low_control - ML,High_control
ML,Low_control - HG,Frog
ML,Low_control - ML,Frog
ML,Low_control - HG,High_control
ML,Low_control - ML,High_control
HG,Frog - ML,Frog
HG,Frog - HG,High_control
HG,Frog - ML,High_control
ML,Frog - HG,High_control
ML,Frog - ML,High_control
HG,High_control - ML,High_control
C. 但我真正想要的是这三个对比,本质上是对比的对比:
1. HG, Low_control - HG, Frog - ML, Low_control - ML, Frog
2. HG, High_control - HG, Frog - ML, High_control - ML, Frog
3. HG, High_control - HG, Low_control - ML, High_control - ML, Low_control
D. 如何在 R 中的混合效应模型的事后测试中为上述三个对比编码?
谢谢!!
