报告摘要: Circulant almost orthogonal arrays (CAOAs) are a class of circulant arrays introduced by Y.-L. Lin, et al. (2017) as designs for fMRI experiments.  In this talk, I will focus on two-level CAOAs with strength 2 and bandwidth 1. I will first talk about the background, statistical models conce-rning CAOAs and their statistical optimality. Moreover, I will introduce the relationship between a special type of CAOAs and combinatorial designs,  as well as binary sequences.  If time permits,  I will briefly address some algebraic and/or computational approaches on finding such CAOAs. This talk is partially based on joint work with Miwako Mishima, Nobuko Miyamoto, and Masakazu Jimbo.
