JSM Keynote Speakers Boast
Impressive Backgrounds
As the ASA membership gears up for JSM 2009, those planning to
attend the annual meetings must decide which sessions to attend and
which activities to undertake. There are many to choose from, but the
keynote addresses are special. Each speaker was chosen specifically for
his or her vast knowledge of statistics and dedicated work in the field.
Here, we introduce these speakers and hope you consider attending
their addresses.
