R语言中混合效应模型结果怎么解释

Question

如题所述

Answer 1

知道是用lme4中的lmer函数，可是结果怎么解释啊，比如
summary(lme(Gmax~1,na.omit(RLC[RLC$Date.set=="herbs",]),random = ~1|Plant/Species))
Linear mixed-effects model fit by REML
Data: na.omit(RLC[RLC$Date.set == "herbs", ])
AIC BIC logLik
4186.307 4199.48 -2089.154

Random effects:
Formula: ~1 | Plant
(Intercept)
StdDev: 0.5173468
