A Bayesian Approach to Estimating the Long Memory Parameter
(Bayesian Analysis, 2009)
We develop a Bayesian procedure for analyzing stationary long-range dependent processes. Specifically, we consider the fractional exponential model (FEXP) to estimate the memory parameter of a stationary long-memory Gaussian ...
Accounting for Uncertainty in Ecological Analysis: The Strengths and Limitations of Hierarchical Statistical Modeling
(Ecological Society of America, 2009)
Analyses of ecological data should account for the uncertainty in the process(es) that generated the data. However, accounting for these uncertainties is a difficult task, since
ecology is known for its complexity. ...
Spatio-Temporal Hierarchical Bayesian Modeling: Tropical Ocean Surface Winds
(American Statistical Association, 2001)
Spatio-temporal processes are ubiquitous in the environmental and physical sciences. This is certainly true of atmospheric and oceanic processes, which typically exhibit many different scales of spatial and temporal ...
Universal Optimality in Balanced Uniform Crossover Design
(Institute of Mathematical Statistics, 2003)
Kunert [Ann. Statist. 12 (1984) 1006-1017] proved that, in the class of repeated measurement designs based on t treatments, p = t periods and n = λt experimental units, a balanced uniform design is universally optimal
for ...
Gene Expression-Based Glioma Classification Using Hierarchical Bayesian Vector Machines
(Indian Statistical Institute, 2007)
This paper considers several Bayesian classification methods for the analysis
of the glioma cancer with microarray data based on reproducing kernel Hilbert space under the multiclass setup. We consider the multinomial ...
Support Points of Locally Optimal Designs for Nonlinear Models with Two Parameters
(Institute of Mathematical Statistics, 2009)
We propose a new approach for identifying the support points of a locally optimal design when the model is a nonlinear model. In contrast to the commonly used geometric approach, we use an approach based on algebraic tools. ...
Strong Consistency of MLE in Nonlinear Mixed-effects Models with Large Cluster Size
(Indian Statistical Institute, 2005)
The search for conditions for the consistency of maximum likelihood estimators in nonlinear
mixed effects models is difficult due to the fact that, in general, the likelihood can
only be expressed as an integral over the ...
ComPhy: Prokaryotic Composite Distance Phylogenies Inferred from Whole-Genome Gene Sets
(BioMed Central, 2009)
With the increasing availability of whole genome sequences, it is becoming more and more important to use complete genome sequences for inferring species phylogenies. We developed a new tool ComPhy, 'Composite Distance ...
On the de la Garza Phenomenon
(Institute of Mathematical Statistics, 2010)
Deriving optimal designs for nonlinear models is, in general, challenging. One crucial step is to determine the number of support points needed. Current tools handle this on a case-by-case basis. Each combination of ...
Population Influences on Tornado Reports in the United States
(Weather and Forecasting, 2005)
The number of tornadoes reported in the United States is believed to be less than the actual incidence of tornadoes, especially prior to the 1990s, because tornadoes may be undetectable by human witnesses in sparsely ...
