Aurore, I don't know if car::Anova is able/should be able to produce anova tables for clmm objects; I usually use drop1() (and sometimes add1) to test terms in CLMMS:
> library(ordinal) > fm1 <- clmm(rating ~ temp + contact + (1|judge), data=wine) > drop1(fm1, test="Chi") Single term deletions Model: rating ~ temp + contact + (1 | judge) Df AIC LRT Pr(>Chi) <none> 177.13 temp 1 209.59 34.464 4.343e-09 *** contact 1 189.48 14.347 0.000152 *** --- Signif. codes: 0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1 Here you get the more accurate likelihood ratio tests instead of the faster and more convenient Wald tests that (if I recall correctly) car::Anova can provide.
