With this tool, you can calculate estimated breeding values (EBV) using Best Linear Unbiased Prediction (BLUP) from a small dataset. You need to specify the heritability of the trait, and you can change the data in the table. When you click “compute EBV”, the tool will give you fixed effect solutions for Herd (or any other group variable), and the EBV for each individual, including their accuracy and rank. Note that this tool should be used for instruction and education purposes only. For more information about EBV, read this blog post.
