I checked what we would have to do to make this possible: Basically, aov_ez
objects contain the multivariate tests provided by class Anova.mlm
from the car
package. The multivariate statistics are computed within the print
method and are never returned in a proper output object by car
(so this is the same problem as with MANOVA objects from car
). A possible solution would be to use the functions used to calculate multivariate statistics (which seem to be copied from the stats
package). Unfortunately, these are not exported, so I think we would have to copy them. Still, because Type 3 sums of squares are ubiquitous in psychology and these are virtually always calculated using car
, I would definitely consider it, especially because the code is very simple and only relies on base
functions.
Thanks for looking into this, Marius! I remember that the essential calculations in the print method had been a road block for these things. Copying the code would be the quick fix option and I'm generally fine with this as an interim solution. But it may be worth proposing a contribution to the car
where, at the least, the function that performs these calculations is exported.
afex
supports calculating multivariate tests for each effect. It would be great if it was possible to report these withapa_print()
.
