lmerTest 没有返回我自己模型的 p 值；所以我试图重现手册中的示例 -
m <- lmer(Informed.liking ~ Gender+Information+Product +(1|Consumer), data=ham)
# gives summary of lmer object. The same as of class merMod but with
# additional p-values calculated based on Satterthwates approximations
summary(m)
但即使这样也能得到消息：
summary from lme4 is returned
some computational error has occurred in lmerTest
并且没有 p 值！怎么了？
提前谢谢！
