关于运行带有比例响应变量的glmm，我有两个问题。 我正在使用从这个问题修改的代码： Errors trying to run glmer with paired data and repeated measures (lme4)
首先，我的代码（数据位于结尾）：
fit2 = glmmPQL(cbind(Ground, 1-Ground) ~ Treatment*Time,
random=~1|Site/Treatment, data=alitter[complete.cases(alitter$Ground),], # removes blanks
family=binomial(link = "logit"), correlation=corCAR1(form = ~Time|Site/Treatment))
Ground是介于0到1（包括0）之间的值。
上面的代码给出以下错误：
Error in Initialize.corCAR1(X[[i]], ...) :
covariate must have unique values within groups for "corCAR1" objects
In addition: Warning message:
In eval(family$initialize) : non-integer counts in a binomial glm!
问题1：我猜这个错误告诉我我的设计不平衡，这是正确的-采样困难意味着必须放弃一些“时间*治疗”组合。如果正确的话，是否有另一种方法可以说明某个站点的重复措施何时完成？
问题2：我不能将线性比例作为响应变量。因此
cbind(Ground, 1-Ground)
那么，我是否正确地完成了这一部分？对于每个比例的地面覆盖物，我都生成了剩余的比例，所以现在每对都加到1。
