Hi Nicola,
In few word: does this row indicate a global effect of the predictor
'cat'
or a more specific passage?
It indicates a more specific passage. Use anova(m7) for global/omnibus.
Check this for yourself by fitting the model with different contrasts. The
default "contrasts" in R are treatment contrasts.
##
m7 <- lmer(log.second ~ Cond + cat + (1|subjID) + (1|Code), data = march.f,
contrasts=list(Cond=contr.treatment,
cat=contr.treatment))
m7s <- lmer(log.second ~ Cond + cat + (1|subjID) + (1|Code), data = march.f,
contrasts=list(Cond=contr.sum, cat=contr.sum))
summary(m7)
summary(m7s)
anova(m7)
anova(m7s)
Regards, Mark.
