R Documentation

AE model using nuclear family trios

Description

This function is adapted from example 7.1 of Rabe-Hesketh et al. (2008). It also procides heritability estimate and confidence intervals.

Usage

AE3(model, random, data, seed = 1234, n.sim = 50000, verbose = TRUE)

Arguments

`model`	a linear mixed model formula, see example below.
`random`	random effect, see exampe below.
`data`	data to be analyzed.
`seed`	random number seed.
`n.sim`	number of simulations.
`verbose`	a flag for printing out results.

Value

The returned value is a list containing:

lme.result: the linear mixed model result.
h2: the heritability estimate.
CL: confidence intervals.

Note

Adapted from f.mbf.R from the paper.
