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).
