BTRY 6940 Graduate Special Topics in Biometry and Statistics
Instructor: Jim Booth
Time: 2:15 PM on Fridays
Place: 1181 Comstock Hall
1 credit
The goal of this class is to review the current state of the literature
on statistical and computational methods for network and pathway discovery in
biological systems.
The class will meet one hour per week. Students signed up for credit will be
expected to do a presentation (say 30 minutes) on a relevant paper or set of
related papers.

Some Stats Seminars of Possible Interest
- November 12 2014 : R. Dennis Cook (University of Minesota) :: Envelopes; Methods for Efficient Estimation in Multivariate Statistics (PDF slides 5.2MB). Further reading on their current initialization algorithm to search over "optimally enveloping Grassmanian" is described in section 4 of http://arxiv.org/abs/1403.4138 and its output is root-n consistent, and it can also be used as a stand-alone method.
