A standard fmri study gives rise to massive amounts of noisy data with a complicated spatio-temporal correlation structure statistics plays a crucial role in understanding the nature of the data and obtaining relevant results that can be used and interpreted by neuroscientists in this paper we discuss the analysis of fmri data. In my previous post i pointed out a major problem with big data is that applied statistics have been left out but many cool ideas in applied statistics are really relevant for big data analysis so i thought i'd try to answer the second question in my previous post: “when thinking about the big data era, what are.
