Occupation and local times for skew Brownian motion with applications to dispersion across an interface

Creator:: Appuhamillage, T. A., Bokil, V. A., Thomann, E., Waymire, E., and Wood, B.
Abstract:: Advective skew dispersion is a natural Markov process defined ned by a di ffusion with drift across an interface of jump discontinuity in a piecewise constant diff usion coeffcient. In the absence of drift this process may be represented as a function of -skew Brownian motion for a uniquely determined...

Estimating agreement coefficients from sample survey data

Creator:: Lin, Hung-Mo, Kim, Hae-Young, Williamson, John M., and Lesser, Virginia M.
Abstract:: We present a generalized estimating equations approach for estimating the concordance correlation coefficient and the kappa coefficient from sample survey data. The estimates and their accompanying standard error need to correctly account for the sampling design. Weighted measures of the concordance correlation coefficient and the kappa coefficient, along with the...

Subsampling Bootstrap of Count Features of Networks

Creator:: Bhattacharyya, Sharmodeep and Bickel, Peter J.
Abstract:: Analysis of stochastic models of networks is quite important in light of the huge influx of network data in social, information and bio sciences, but a proper statistical analysis of features of different stochastic models of networks is still underway.We propose bootstrap subsampling methods for finding empirical distribution of count...

Estimation and model selection in generalized additive partial linear models for correlated data with diverging number of covariates

Creator:: Wang, Li, Xue, Lan, Qu, Annie, and Liang, Hua
Abstract:: We propose generalized additive partial linear models for complex data which allow one to capture nonlinear patterns of some covariates, in the presence of linear components. The proposed method improves estimation efficiency and increases statistical power for correlated data through incorporating the correlation information. A unique feature of the proposed...

Advection–Dispersion Across Interfaces

Creator:: Ramirez, Jorge M., Thomann, Enrique A., and Waymire, Edward C.
Abstract:: This article concerns a systemic manifestation of small scale interfacial heterogeneities in large scale quantities of interest to a variety of diverse applications spanning the earth, biological and ecological sciences. Beginning with formulations in terms of partial differential equations governing the conservative, advective-dispersive transport of mass concentrations in divergence form,...

Variable Selection in High-dimensional Varying-coefficient Models with Global Optimality

Creator:: Xue, Lan and Qu, Annie
Abstract:: The varying-coefficient model is flexible and powerful for modeling the dynamic changes of regression coefficients. It is important to identify significant covariates associated with response variables, especially for high-dimensional settings where the number of covariates can be larger than the sample size. We consider model selection in the high-dimensional setting...

GIScience

Creator:: Wright, Dawn J.
Abstract:: GIScience (geographic information science) is a scholarly discipline that addresses fundamental issues surrounding the use of a variety of digital technologies to handle geographic information; namely, information about places, activities, and phenomena on and near the surface of the Earth that are stored in maps or images. GIScience includes the...
