Function used in the proLik function to produce a profile likelihood for a variance component

Description

Given a model object from asreml and a range of estimates of the parameter, the function will supply the likelihood ratio test statistic for the comparison of the full model to one where the parameter of interest is constrained.

Usage

parConstrainFun(x, parameters, full, fm2, comp, G)

Arguments

x	section of all parameter values to analyze
parameters	a value for which the log Likelihood of a model is to be calculated
full	the full model asreml object
fm2	starting values for the full model
comp	which variance component to constrain
G	logical indicating if the component is part of the G structure

Details

Used internally in the proLik function to call constrainFun
