Dr Shehzad Khalid; Shahid Razzaq
(Bahria University Islamabad Campus, 2015)
This paper identifies a previously undiscovered behavior of uniformly distributed data points or vectors in high dimensional ellipsoidal models. Such models give near normal distributions for each of its dimensions. Converse ...
