summary
and anova
method are copied from the lmerTest
package in order to have p-values.
Given 2 factors, f
and g
, and a grouping variable id
, the formula (1|id) + (1|id:f)+ (1|id:g)+ (1|id:f:g)
can be reduced to (1|id|f*g)
. However the grouping variable (herer id
) should be written as one variable.
