the position of the last endogenous variable (by default the last column of donnee
random
boolean, effect should be possible as fixed or random (default as random)
Details
The formul parameter must be filled in by an analysis of variance model and must
begin with the categorical variable of interest (e.g. the product effect)
followed by the different other factors of interest (and their combinations).
E.g.:formul = "~Product+Session".
Value
A list containing the following components:
p.value
a matrix of dimension (k,m) of P-values associated with the F-test for the
k descriptors and the m factors and their combinations considered in the analysis
of variance model of interest
variability
a matrix of dimension (k,m) where the entries correspond to the percentages of variability
due to the effects introduced in the analysis of variance model of interest
res
a vector of dimension k of residual terms for the analysis
of variance model of interest
r2
a vector of dimension k of r-squared for the analysis of variance model of interest
