- | This is program is used to do cross-validations. It reads a blupf90 parameter file, a solutions file | ||
- | and a data file | ||
- | It needs '' | ||
- | It computes | ||
- | y_hat = sum of estimates of the included effects | ||
- | y_star = y corrected by the other (not included) effects | ||
- | residual = y - included effects (not a true residual) | ||
- | |||
- | For instance consider | ||
- | |||
- | y = herd + age + animal + e | ||
- | |||
- | with '' | ||
- | |||
- | y_hat = animal_hat | ||
- | ystar = y - herd_hat - age_hat | ||
- | Which makes cor(y_hat, | ||
- | |||
- | it outputs the correlation between y_hat and y_star, for instance cor(ystar, | ||
- | |||
- | and outputs these columns into a file, together with animal id (if there is animal in the model) or record number (if not) | ||
- | |||
- | In addition, if animal effect is in the model, it produces a file with ebvs from the solutions file. |
