使用包 lme4 拟合“glmer”模型时,以下警告消息的含义是什么?
Warning messages:
1: glm.fit: fitted probabilities numerically 0 or 1 occurred
2: In mer_finalize(ans) : false convergence (8)
我试图拟合的模型是这样的:
glmer(dummy ~ constituency.coa + I(governat.part) + I(district2) + gdp.cap + lula.power + ifdm + bf.cap + year + (1 | munname), data=pool, family=binomial(link = "logit"), REML=T, verbose=T)
谢谢
