+**predictf90**
+This is program is used to do cross-validations. It reads a blupf90 parameter file, a solutions file
+and a data file
+It needs ''OPTION include_effects'' followed by a series of effects.
+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 ''OPTION include_effects 3''
+y_hat = animal_hat
+ystar = y - herd_hat - age_hat
+Which makes cor(y_hat,y_star) = cor(ebv, corrected y) which is a measure of accuracy
+it outputs the correlation between y_hat and y_star, for instance cor(ystar,yhat)=cor(u+e, uhat)
+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.
