Largest matrix to invert | V, phenotypic variance-covariance matrix | C, coefficient matrix of MME | |
Size of largest matrix to invert | q × q, assuming one observation per individual | c + 2q for C | |
Largest matrix to store in memory | q × q P matrix | c + 2q for C | |
Applicable to singular genomic relationship matrices | Yes, inverse relationship matrices avoided | No, inverse relationship matrices required | |
