High Dimensional Statistics - MIT Mathematics
Statistics at MIT. They build on a set of notes that was prepared at Prince-ton University in 2013-14 that was modi ed (and hopefully improved) over the years. Over the past decade, statistics have undergone drastic changes with the development of high-dimensional statistical inference. Indeed, on each indi-
