R: Class '"MxFitFunctionGREML"'

MxFitFunctionGREML-class {OpenMx} | R Documentation

## Class `"MxFitFunctionGREML"`

### 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).

`numObs`:

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

`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.

`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

Class `"MxBaseFitFunction"`, directly. Class `"MxBaseNamed"`, by class "MxBaseFitFunction", distance 2. Class `"MxFitFunction"`, by class "MxBaseFitFunction", distance 2.

### Methods
