Use this field to specify the variables containing columns of the square root of the

K matrix, which is a matrix containing

kinship coefficients computed using either the

Relationship Matrix or

Kinship Matrix processes.

Note: If a

Pedigree ID Variable is not specified, this matrix should contain the same number of variables as

observations in the input data set. When a

pedigree ID variable is specified, this matrix should have the same number of variables as the number of individuals in the largest pedigree in the data set.
