Discussion of Likelihood Inference for Models with Unobservables: Another View
Discussion Likelihood Inference Models Unobservables Another View
2010/10/15
Lee and Nelder identify important issues and provide excellent advice and warnings associated with inferences and interpretations for models with unobserved, latent variables (random effects). Their d...
We introduce an extension of the P\'olya tree approach for constructing distributions on the space of probability measures. By using optional stopping and optional choice of splitting variables, the ...
Inference and Modeling with Log-concave Distributions
Nonparametric density estimation shape constraint log-concave density Polya frequency function
2010/10/14
Log-concave distributions are an attractive choice for modeling and inference, for several reasons: The class of log-concave distributions contains most of the commonly used parametric distributions ...
Likelihood Inference for Models with Unobservables: Another View
Hierarchical generalized linear model unobservables random effects likelihood
2010/10/14
There have been controversies among statisticians on (i) what to model and (ii) how to make inferences from models with unobservables. One such controversy concerns the difference between estimation ...
Inference on Eigenvalues of Wishart Distribution Using Asymptotics with respect to the Dispersion of Population Eigenvalues
eigenvalues of covariance matrix Wishart distribution test on eigenvalues interval estimation of eigenvalues
2010/4/28
In this paper we derive some new and practical results on testing and interval estimation
problems for the population eigenvalues of a Wishart matrix based on the asymptotic theory
for block-wise in...
Statistical inference for multidimensional time-changed Lévy processes based on low-frequency data
time-changed Levy processes dependence minimax rates of convergence lowfrequency observations
2010/3/11
In this article we study the problem of a semi-parametric inference on the parameters of
a multidimensional L´evy process Lt based on the low-frequency observations of the corresponding
time-c...
Asymptotic inference for high-dimensional data
Covariance matrix estimation c0 functional genomics highdimensionaldata infinite-dimensional central limit theorem
2010/3/10
In this paper, we study inference for high-dimensional data characterized
by small sample sizes relative to the dimension of the data.
In particular, we provide an infinite-dimensional framework to ...
This chapter provides a overview of Bayesian inference, mostly emphasising that it is a
universal method for summarising uncertainty and making estimates and predictions using
probability statements...
Inference based on Procrustes means for the 3D shape of tree boles and mildly rank-deficient diffusion tensors
Shape Spaces Extrinsic Mean Mean Location GeneralProcrustes Analysis Weighted Procrustes Mean Strong Law of Large Numbers
2010/3/10
A method for inference on cylindricity of tree boles based on 3D
Kendall shapes is presented. This method employs Procrustes means
which are highly popular in the shape community. While for extrinsi...
Inference in HIV dynamics models via hierarchical likelihood
algorithm asymptotic di erential equations h-likelihood HIV dynamics models non-linear mixed e ects model penalized likelihood.
2010/3/10
HIV dynamical models are often based on non-linear systems
of ordinary di erential equations (ODE), which do not have analytical
solution. Introducing random e ects in such models leads to very chal...
On the inference of large phylogenies with long branches:How long is too long?

2010/3/9
The accurate reconstruction of phylogenies from short molecular sequences
is an important problem in computational biology. Recent work has highlighted
deep connections between sequence-length requi...

Inference in incidence, infection, and impact: Co-infection of multiple hosts by multiple pathogens
DNA sequencedata forest dynamics Janzen Connell hypothesis species diversity variable selection
2009/9/24
A large literature concerns the epidemiology of single pathogens on single hosts. Yet in some environmental applications, such as fungal pathogens of forest tree seedlings, the “one host-one...
Inference for MA(1) processes with a root on or near the unit circle
Inference for MA(1) processes a root on or near the unit circle
2009/9/22
This paper considers maximum likelihood estimation
(MLE) for MA(1) processes when the moving average parameter is on
or near the unit circle. The asymptotic theory to be presented allows
the use of...
Bayesian inference for the MAPK/ERK pathway by considering the dependency of the kinetic parameters
MCMC MAPK/ERKpathway diusion approximation data augmentation dependency in diusion matrix
2009/9/22
The MAPK/ERK pathway is one of the major signal transduction systems which regulates the cellular growth control of all eukaryotes like the cell proliferation and the apoptosis. Because of its importa...
