Standardize Predictors Row-Wise
Specify this option to standardize the predictor variables rowwise. This results in a correlation matrix instead of a sums-of-squares-and-products matrix being used to form the covariance matrix in the model. When you are using standardized genotypes as predictors, this option results in using the IBD K matrix in your model as is computed in Relationship Matrix and used in Q-K Mixed Model.
