Statistical Methods for Animal Science and Breeding

In this project, we are evaluating how statistical methods can be used for genomic analyses and using pooled data in genetic evaluations, and defining novel traits. In addition, a major component of this project is on using appropriate statistical procedures and experimental designs in Animal Science Research and on evaluating/improving the statistical competency of graduate students.
