Scientists explore new statistical tools

More than 4500 statisticians gathered at the Joint Statistical Meetings 2012 – one of the world’s largest fora in the profession – held last month in San Diego, California. ICARDA was represented by Dr Murari Singh, who presented a paper on Bayesian techniques to estimate shrub species diversity in arid rangeland areas. The study, co-authored by Mr Abdoul Aziz Niane (ICARDA) and Dr Paul Struik (Wageningen University, the Netherlands), analyzed species abundance at two sites in the Syrian rangelands under two grazing management systems – areas open to and protected from grazing – to better understand the effects of rainfall and grazing patterns on plant diversity.

Presentations at the meeting covered a range of subjects. Of particular relevance to ICARDA were the sessions on Bayesian approaches to analyze data at different scales; genome-wide SNP marker trait associations; regional climate models; and G x E interaction analysis. The meeting was co-organized by the American Statistical Association, the International Biometric Society, and research institutes and associations from Canada, China and India.
