Description

MxFitFunctionGREML is the fitfunction class for GREML analyses.

Objects from the Class

Objects can be created by calls of the form mxFitFunctionGREML(dV).

Slots

dV:

Object of class "MxCharOrNumber". Identifies the MxAlgebra or MxMatrix object(s) to serve as the derivatives of 'V' with respect to free parameters.

dVnames:

Vector of character strings; names of the free parameters corresponding to slot dV.

MLfit:

Object of class "numeric", equal to the maximum-likelihood fitfunction value (as opposed to the restricted maximum-likelihood value).

numObsAdjust:

Object of class "integer". Number of observations adjustment.

aug:

Object of class "MxCharOrNumber". Identifies the MxAlgebra or MxMatrix object used to "augment" the fitfunction value at each function evaluation during optimization.

augGrad:

Object of class "MxCharOrNumber". Identifies the MxAlgebra or MxMatrix object(s) to serve as the first derivatives of aug with respect to free parameters.

augHess:

Object of class "MxCharOrNumber". Identifies the MxAlgebra or MxMatrix object(s) to serve as the second derivatives of aug with respect to free parameters.

autoDerivType:

Object of class "character". Dictates whether fitfunction derivatives automatically calculated by OpenMx should be numeric or "semi-analytic."

infoMatType:

Object of class "character". Dictates whether to calculate the average or expected information matrix.

info:

Object of class "list".

dependencies:

Object of class "integer".

expectation:

Object of class "integer".

vector:

Object of class "logical".

rowDiagnostics:

Object of class "logical".

result:

Object of class "matrix".

name:

Object of class "character".

Extends
