Workshop on Empirical Likelihood Methods<br />
May 9–11, <strong>2005</strong><br />
Held at the <strong>University</strong> <strong>of</strong> Ottawa<br />
Organizers: Mayer Alvo (Ottawa) and Jon Rao (Carleton)<br />
Inference based on likelihood methods has proven very<br />
effective in the past. The methods can be used for constructing<br />
tests with good asymptotic properties, confidence<br />
intervals with accurate coverage probability as well as<br />
to pool data from different sources. Unfortunately in<br />
parametric statistics one must suppose that the underlying<br />
family <strong>of</strong> distributions is known, save for some parameters<br />
which are estimated from the data. The use <strong>of</strong> parametric<br />
methods when the underlying distributions are unknown<br />
can lead to incorrect tests and inaccurate confidence intervals.<br />
Empirical Likelihood has been applied successfully in<br />
determining confidence intervals whose shape and orientation<br />
is dictated by the data. These intervals also respect the<br />
range <strong>of</strong> the parameter space. The method has proven effective<br />
in audit sampling where lower confidence bounds are<br />
used to compute the amount <strong>of</strong> money owed to government<br />
for example. The empirical confidence intervals outperformed<br />
the parametric likelihood intervals by providing<br />
large lower bounds respecting the nominal error rate.<br />
Art Owens (Stanford) presented a tutorial on empirical<br />
likelihood methods. This was followed by presentations<br />
by Jon Rao, Jiahua Chen, Changbao Wu, P.K.Sen, Mayer<br />
Alvo, Qunshu Ren and Yongson Quin. There was a good<br />
exchange <strong>of</strong> ideas throughout the workshop, which will<br />
undoubtedly translate into a vigorous research in this<br />
growing field.<br />
