ehSetBase {CoCoRaw} | R Documentation |
Set the base model of the EH procedure.
Tests of models in the EH procedure are performed
against the saturated model, or the
model entered by ehSetBase
.
ehSetBase(model = FALSE, data = NULL, object = .object.of.model(model, data = data, ...), ...)

The base model of the EH procedure effects fixing in
the EH procedure, ehForceFix
.
Terms not in the base model of the EH procedure
are set to be fixed out for the EH procedure,
e.i., the fixing out is set to the dual representation
of the model set by ehSetBase
.
Since there is no distinction between fixing out due to
ehForceFix(gc, fix = "out", ...)
and due to
ehSetBase
, and since a larger EH base model
would give less fixing out in the EH procedure,
previous fixing out in the EH procedure is canceled
by ehSetBase
.
Use ehForceFix(fix = "out", redo = TRUE, ...)
to
redo the fixing out in the EH procedure.
Only terms in the base model of the EH procedure
can be fixed into the EH procedure.
Thus terms set by ehForceFix(gc, fix = "in", ...)
might be reduced by ehSetBase
.
