Wald F statistics
Conditional F statistics
!FCON
adds a 'conditional' F-statistic column to the
table of Wald F statistics. It enables inference for fixed effects in the
dense part of the linear mixed model to be conducted so as to
respect both structural and intrinsic marginality.
The detail of exactly which terms are conditioned on
is reported in the
.aov
file.
The principle used in determining this conditional test
is that a term cannot be adjusted for another term which encompasses it
explicitly (e.g. term
A.C
cannot be adjusted for
A.B.C
)
or implicitly (e.g. term
REGION
cannot be adjusted for
LOCATION
when locations are actually nested in regions although they are
coded independently).
