NMAK14007U Asymptotic theory
MSc Programme in Statistics
MSc Programme in Mathematics-Economics
Asymptotic mathods in statistics are approximation results for
the distributions of estimators and test statistics, valid as the
number of observations tend to infinity. The basic asymptotic
result is the Central Limit Theorem, which concerns sums of
independent or weakly dependent stochastic variables.
However, interesting constructions in statistics are usually not
sums, at least not in any transparent way. So a certain amount of
work is needed to identify relevant sums of variables, and to make
sure that these sums indeed control the behaviour of the
constructions of interest.
The course will focus on rigorous derivations of asymptotic results
for M-estimators, a very large class encompassing most estimation
procedures in common use. We will also consider several subclasses
of M-estimators in detail. The course will also contain an
introduction to higher order asymptotic theory, relying on
modifications of the underlying CLT. If time permits we will
explore the connection between the asymptotic results
and the arguments behind the use of informations
criteria in model selection
Competence: analyse the statistical implications of a range of
asymptotic sampling scenarios
Skills:
* Adapt methods based on CLT to practical M-estimation
scenarios.
* Derive and check regularity conditions for the general
M-estimation results to hold in concrete examples
Knowledge:
* The central limit theorem and various extensions
* Classes of concordance functions giving rise to
M-estimation problems: likelihood, profile likelihood, partial
likelihood , composite likelhood, robust criteria.
