Accuracy of calculations of comparative standards for milk yield as a function of the number of animals. I. Development and evaluation of the model


, : Accuracy of calculations of comparative standards for milk yield as a function of the number of animals. I. Development and evaluation of the model. Archiv fur Tierzucht 15(6): 399-405

Assuming a normal distribution of lactation yields, a model relationship was devised according to which the min. number of animals necessary for computing a comparative standard for milk yield (based on the arithmetic mean of individual performances), was inversely proportional to the square of the admissible error.
