ehSetBase {CoCoRaw}R Documentation

The base model of the EH procedure

Description

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.

Usage

ehSetBase(model = FALSE, data = NULL,
          object = .object.of.model(model, data = data, ...), ...)

Arguments

model See returnModel.
data See exportCoCo.
object See exportCoCo.
... Additional arguments to generate the CoCo object from the data argument. See propertyModel.

Value

TRUE

Note

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.
