R help - Aug 2008 - How to get the p-value from lmer on a longitudinal analysis

Hi,

I have a modelo like this:

Yvar <- c(0, 0, 0, 0, 1, 0, 0, 0, 1, 2, 1, 1, 2, 3, 6, 6, 3, 3, 4)
TIME <- 4:22
ID <- rep("PlotA",19)
m <- lmer(Yvar~TIME+(TIME|ID),family=poisson)
anova(m)
summary(m)

How to get the p-value for this case?

Thanks
Ronaldo

Unless something has changed recently:

Hi Ronaldo,

... lmer p-values

There are two packages that may help you with this and that might work with
the current implementation of lmer(). They are languageR and RLRsim.

HTH, Mark.
