This function estimates the genetic and the environmental variance components and the covariate effects using ANOVA and GLS approaches respectively.
1 | ANOVA.estimators.COV(ntype, beta, X, Y, kin.miss)
|
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. |
beta |
Ordinary least squares estimates of the covariate effects. |
X |
Model design matrix. |
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 |
kinship matrix as a list with length the total number of families. Eeach object of the list represents a family kinship matrix. |
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 |
