What Does the Term Accuracy Mean and Why is it Valuable ot Producers?

Jared Decker (University of Missouri): EPD accuracy is a measure of the precision or the reliability of that EPD estimate. It's a measure of how close that animal's EPD estimate is to the true breeding value. It's really a measure of how well we are predicting the EPD for that animal and how much information is going into that prediction. The accuracy gives us a measure of how much that EPD can change as we collect more information. So, if a bull has a low accuracy EPD, that EPD estimate can change, quite significantly, as we collect more information. If that bull has a high accuracy EPD, the possible change for that estimate is quite small.
