Research Abstract

We organized and hosted an international symposium “Life Science and Statistics” in Osaka University in 2011, the first year of the research. The symposium was held to aim at constructing an interface among researchers in statistics, life science, cognitive psychologyand brain sciences. At least two joint international works have been accomplished, as fruits of having the symposium; one is on a new estimation of factor analysis model and the other on a new factor rotation method. After the symposium, a new research group of statisticians and brain scientists was created to conduct an interdisciplinary study.
