+ | ==== More explanation ==== | ||
+ | |||
+ | This program splits the phenotype (y) into 3 pieces. | ||
+ | |||
+ | y = (effects to be corrected) + (effects to be kept) + residual | ||
+ | |||
+ | In a cross validation, you need a quantity "EBV + residual", | ||
+ | The program calculates the following quantities. | ||
+ | |||
+ | * y_hat: '' | ||
+ | * y_star: '' | ||
+ | * residual: '' | ||
+ | |||
+ | The user should specify the effects to be kept using '' | ||
+ | For example, if the breeding value is in the 3rd row in the EFFECTS section in the parameter file, you have to use '' | ||
