Large Scale Correlation Screening


Jun 26, 2011
Alfred O. Hero, Bala Rajaratnam

* 33 pages, 7 figures; Changes in version 2: There are no changes in the technical material in this revised version. The only changes are correcting typographical errors and referencing related work in the area. There is also material in the introduction where more context to the correlation screening problem is given (especially in terms of relationships to other testing methods)
