我想为响应变量的某些解释变量（称为HUNTED）生成置信区间的值。数据约为3个不同的时间周期。 但是，当我使用代码时： 图书馆（MASS） confint（allspecies4） 我只收到错误消息（见下文）。有谁知道如何改善我的脚本，以便我可以进入置信区间？ 观察：我的数据集太大了，我只添加了一部分，以便您了解其分布情况。
allspecies4<-read.csv(file= "dadosGLMM.csv", header= TRUE, sep= ";" )
attach(allspecies4)
library(lme4)
allspecies4<- glmer(HUNTED~ eco+TrophicLevel+age+ log(body_mass)+
habitat+ABUND + PERIOD + tabu +(1|Specie),
data=dadosGLMM, family=binomial)
