In some multistratum anova, treatment factors are not orthogonal to
error strata, and there is partial information for a treatment
in more than one strata.
Typically, the most efficient strata is
the lowest strata in which the treatment occurs.
The relative efficiencies measure the proportion of
the treatment that projects onto each error stratum.
Efficiencies affect the computation of fitted effects,
means and their standard errors (see
model.tables
).
The computation requires the
qr
component of the
aovlist
object.
