通过效果包对lmer对象的置信区间的可信度如何?
Effects包提供了一种非常快速和方便的方式来绘制通过lme4包获得的线性混合效应模型结果。该effect函数可以非常快速地计算置信区间(CI),但是这些置信区间的可信度如何? 例如: library(lme4) library(effects) library(ggplot) data(Pastes) fm1 <- lmer(strength ~ batch + (1 | cask), Pastes) effs <- as.data.frame(effect(c("batch"), fm1)) ggplot(effs, aes(x = batch, y = fit, ymin = lower, ymax = upper)) + geom_rect(xmax = Inf, xmin = -Inf, ymin = effs[effs$batch == "A", "lower"], ymax = effs[effs$batch == …
