Bias
Let u be the true progeny difference (TPD) and u^ be our estimate (EPD). From this we could estimate the degree of bias in our estimate by determining the difference in the mean u and mean u^. However, we never observe the TPD. Instead we estimate it using pedigree, performance, and genomic data.
