ANOVA.estimators: Variance components estimators

In KarimOualkacha/PCH4Pedigees: Principal Components of Heritability for High Dimension Quantitative Traits and General Pedigrees

Description

This function estimates the genetic and the environmental variance components using an ANOVA approach.

Usage

ANOVA.estimators(ntype, Y, kin.miss)

Arguments

ntype	Vector of integers. Its length equals to the total number of families used in the pedigree file. The ntype's entries are the total number of subjects within each family.
Y	List of matrices obtained from the function ANOVA.data(). Its length equals to the number of families used in the study. Each matrix of this list represents one family of the pedigree file (i. e. each list entry has subjects of a same family as rows and their corresponding traits as columns).
kin.miss	List of matrices. Its length equals to the total number of families. The list entries represent the family kinship matrices.

Value

nnd.Mnt.e	Environmental variance-covariance matrix
nnd.Mnt.g	Genetic variance-covariance matrix
SSW	Subject-specific variance-covariance matrix
SSB	family-specific variance-covariance matrix
