MxExpectationGREML-class: Class "MxExpectationGREML"

In OpenMx: Extended Structural Equation Modelling

Class "MxExpectationGREML"

Description

MxExpectationGREML is a type of expectation class. It contains the necessary elements for specifying a GREML model. For more information, see mxExpectationGREML().

Objects from the Class

Objects can be created by calls of the form mxExpectationGREML(V, yvars, Xvars, addOnes, blockByPheno, staggerZeroes, dataset.is.yX, casesToDropFromV).

Slots

V:

Object of class "MxCharOrNumber". Identifies the MxAlgebra or MxMatrix to serve as the 'V' matrix.

yvars:

Character vector. Each string names a column of the raw dataset, to be used as a phenotypes.

Xvars:

A list of data column names, specifying the covariates to be used with each phenotype.

addOnes:

Logical; pertains to data-handling at runtime.

blockByPheno:

Logical; pertains to data-handling at runtime.

staggerZeroes:

Logical; pertains to data-handling at runtime.

dataset.is.yX:

Logical; pertains to data-handling at runtime.

y:

Object of class "MxData". Its observed slot will contain the phenotype vector, 'y.'

X:

A matrix, to contain the 'X' matrix of covariates.

yXcolnames:

Character vector; used to store the column names of 'y' and 'X.'

casesToDrop:

Integer vector, specifying the rows and columns of the 'V' matrix to be removed at runtime.

b:

A matrix, to contain the vector of regression coefficients calculated at runtime.

bcov:

A matrix, to contain the sampling covariance matrix of the regression coefficients calculated at runtime.

numFixEff:

Integer number of covariates in 'X.'

dims:

Object of class "character".

numStats:

Numeric; number of observed statistics.

dataColumns:

Object of class "numeric".

name:

Object of class "character".

data:

Object of class "MxCharOrNumber".

.runDims:

Object of class "character".

Extends
