The 2nd East Asian Workshop on Astrostatistics were held on July 9-13,2018 at Purple Mountain Observatory of CAS (PMO) in Nanjing, and on July 16-20, 2018 at Guizhou Normal University in Guiyang. This workshop is supported by East Asian Core Observatories Association (EACOA), and organized by National Astronomical Observatories of CAS (NAOC), PMO and Guizhou Normal University. A total of 129 participants from 28 astronomical research institutes of China, Japan, Vietnam and Mongolia attended the workshop.

EACOA consists of four core observatories in East Asian, including NAOC, National Astronomical Observatory of Japan (NAOJ), Korea Astronomy and Space Science institute (KASI), and Academia Sinica Institue of Astronomy and Astrophysics (ASIAA). It is formed to foster and coordinate collaborations between the major astronomical observatories in the region. The 1st East Asian Workshop on Astrostatistics was organized by NAOJ in 2017.

This workshop provides astronomers and students in China, as well as in other East Asian regions, with an opportunity to learn about using statistical methods and R language for the analysis and evaluation of modern astronomical data. Prof. Eric Feigelson from Penn State University is the instructor of the workshop. Prof. Feigelson is inaugural president of the International Astronomical Union Commission on Astroinformatics and Astrostatistics.  He runs annual summer schools in statistics for astronomers since 2005 and authored the award-winning graduate textbook Modern Statistical Methods for Astronomy with R Applications. In the workshop, Prof. Feigelson covered the topics of density estimation & local regression, statistical inference, regression, multivariate clustering & classification, Bayesian inference, time series analysis, good statistical practices in astronomy, and illustrated by code examples.
