Create an mxModel for a pedigree

This function builds an OpenMx model for a pedigree with specified variance components. It requires the OpenMx package.

Usage

buildPedigreeModelCovariance(
  vars = list(ad2 = 0.5, dd2 = 0.3, cn2 = 0.2, ce2 = 0.4, mt2 = 0.1, am2 = 0.25, ee2 =
    0.6),
  Vad = TRUE,
  Vdd = FALSE,
  Vcn = TRUE,
  Vce = TRUE,
  Vmt = TRUE,
  Vam = FALSE,
  Ver = TRUE
)

Arguments

vars

A named list or vector of initial variance component values. Names should include ad2 (additive), dd2 (dominance), cn2 (common nuclear), ce2 (common extended), mt2 (mitochondrial), am2 (additive-mitochondrial interaction), and ee2 (unique environment). Default values are provided.

Vad

Logical. Include additive genetic variance component. Default is TRUE.

Vdd

Logical. Include dominance genetic variance component. Default is FALSE.

Vcn

Logical. Include common nuclear family environment variance component. Default is TRUE.

Vce

Logical. Include common extended family environment variance component. Default is TRUE.

Vmt

Logical. Include mitochondrial genetic variance component. Default is TRUE.

Vam

Logical. Include additive by mitochondrial interaction variance component. Default is FALSE.

Ver

Logical. Include unique environmental variance component. Default is TRUE.

Value

An OpenMx model representing the pedigree with specified variance components.
