solveRRBLUP_EM {AlphaSimR}

Solve RR-BLUP with EM

Description

Solves a univariate mixed model of form y=X\beta+Mu+e using the Expectation-Maximization algorithm.

Usage

solveRRBLUP_EM(Y, X, M, Vu, Ve, tol, maxIter, useEM)

Arguments

Y

a matrix with n rows and 1 column

X

a matrix with n rows and x columns

M

a matrix with n rows and m columns

Vu

initial guess for variance of marker effects

Ve

initial guess for error variance

tol

tolerance for declaring convergence

maxIter

maximum iteration for attempting convergence

useEM

should EM algorithm be used. If false, no estimation of variance components is performed. The initial values are treated as true.
