quass R Documentation
Compute the inverse of the additive relationship matrix using Quass algorithm
Description
Given the vectors of sire and dam, directly return inverse of additive relationship matrix 'A' without creating the 'A' itself.
This is a modification of Henderson's method and unlike createAinv.r, this can be used in inbred populations.
Reference:
Quass, R. L. 1976. Computing the Diagonal Elements and Inverse of a Large Numerator Relationship Matrix. Biometrics 32:949-953.
Usage
quass(s, d)
Arguments
s
vector of sires
d
vector of dams
Value
matrix
Note
Unknown parents should be coded as zero. Last modified by Morota on April 2, 2010.
