AAS Special Sessions in AstroStatistics
HEAD 2000: Special Tutorial Workshop
On Beyond Chi^2 (and Bevington):
Making the Most of Your Poisson Data
Our panel is a mixture of statisticians,
those building software for data analysis; and astrophyscists.
Each will briefly go through new methods and old problems
from a range of wave-lengths;
and open it up to a lot of discussion ("I can't believe the F-test
doesn't work for finding asorption lines in my spectrum! I've been
using it for decades!" "Do you mean there's a better way to test for
a periodic signal in my TeV data?" etc etc etc)
Format:
Invited Oral Panel (chair; Aneta Siemiginowska)
