The Distribution of Time Spent by a Standard Excursion Above a Given Level, with Applications to Ring Polymers near a Discontinuity in Potential
Standard Brownian Excursions Brownian Bridges Ring Polymers End-Attached Polymers
2009/5/8
The law for the time tau_{a} spent by a standard Brownian excursion above a given level a>0 is found using Ito excursion theory. This is achieved by conditioning the excursion to have exactly one mark...
Moment identities for Skorohod integrals on the Wiener space and applications
Malliavin calculus Skorohod integral Skorohod isometry Wiener measure random isometries
2009/4/29
We prove a moment identity on the Wiener space that extends the Skorohod isometry to arbitrary powers of the Skorohod integral on the Wiener space. As simple consequences of this identity we obtain su...

Inference for Partially Observed Multitype Branching Processes and Ecological Applications
Parametric inference Incomplete data Multitype branchingprocesses ecology
2010/3/18
Multitype branching processes with immigration in one type are
used to model the dynamics of stage-structured plant populations.
Parametric inference is first carried out when count data of all type...

We consider the model Zi = Xi + εi, for i.i.d. Xi’s and εi’s and independent sequences (Xi)i2Nand (εi)i2N. The density f" of ε1 is assumed to be known, whereas the one of X1, denoted by
g, is unknown...
A mixture of experts model for rank data with applications in election studies
Rank data mixture models generalized linear models EMalgorithm MM algorithm

A voting bloc is defined to be a group of voters who have similar
voting preferences. The cleavage of the Irish electorate into voting
blocs is of interest. Irish elections employ a “single transfer...
Nonparametric spectral analysis with applications to seizure characterization using EEG time series

Exponential inequalities for self-normalized martingales with applications
Exponential inequalities martingales autoregressive processes branching processes
2010/4/30
We propose several exponential inequalities for self-normalized
martingales similar to those established by De la Pe˜na. The keystone
is the introduction of a new notion of random variable heav...
Controlling for individual heterogeneity in longitudinal models，with applications to student achievement
longitudinal data analysis random effects models fixed effects models omitted variables
2010/4/29
Longitudinal data tracking repeated measurements on individuals are
highly valued for research because they offer controls for unmeasured individual
heterogeneity that might otherwise bias results. ...
A comparison of statistical models for short categorical or ordinal time series with applications in ecology
time series categorical variable ordinal variable regression model Markov chain auto-regressive process estimation
2010/4/27
We study two statistical models for short-length categorical (or ordinal) time series. The first one is a regression
model based on generalized linear model. The second one is a parametrized Markovia...

In this paper, a very useful lemma (in two versions) is proved: it simplifies
notably the essential step to establish a Lindeberg central limit theorem
for dependent processes. Then, applying this l...
