應管理與經(jīng)濟學院的邀請，美國國立衛(wèi)生研究院資深研究員、Georgetown University兼職教授、泛華統(tǒng)計協(xié)會主席劉愛義（AiYi Liu）來偉德國際官網(wǎng)進行交流訪問，并于2018年6月26日上午在主樓216會議室進行了題為《On the Efficiency of Group Testing and Retesting for Estimating Rare Events》的學術(shù)報告，報告會由會計系李慧云教授主持。
AiYi Liu首先介紹了他的研究成果，包括Group Testing及Retest的研究背景、理論基礎(chǔ)、研究結(jié)果、實際應用等方面。之后的提問交流環(huán)節(jié)中，AiYi Liu耐心地解答了老師和同學們提出的問題，與大家進行了深入探討。AiYi Liu與同學們分享了他的研究經(jīng)驗和心得體會，并就如何在管理、實證會計研究中應用統(tǒng)計知識、如何進行高水平研究及論文寫作，提出了許多寶貴意見，得到了同學們的熱情回應。
整場交流活動內(nèi)容豐富，在場的研究生收獲頗豐。統(tǒng)計方法作為一種工具被廣泛的用于管理、經(jīng)濟等眾多領(lǐng)域。AiYi Liu從統(tǒng)計方法的重要性著手，提出了Group Testing及Retest可能在管理中的應用方向，不僅在理論上帶給我們諸多啟發(fā)，也對我們的實際研究提供了許多有價值的參考意見。
