Animal Biologics Statisticians

Animal Biologics Statisticians is an unofficial and unaffiliated group of individual statisticians interested in the application of statistical methods to animal biologics. In support of this endeavor, the ABS-dev subgroup maintains a github page to share examples of R code and packages we find of interest. Since these examples are not official products, the possible similarity of some of the methods to those used by official bodies may be useful for pedagogical purposes only, unless otherwise stated.
