Clustering-Based Inter-Regional Correlation Estimation
Hanâ Lbath, Alexander Petersen, Wendy Meiring +1
A novel non-parametric estimator of the correlation between grouped measurements of a quantity is proposed in the presence of noise. This work is primarily motivated by functional…
Predicting Distributions of Physical Activity Profiles in the NHANES Database Using a Partially Linear Fréchet Single Index Model
Marcos Matabuena, Aritra Ghosal, Wendy Meiring +1
Object-oriented data analysis is a fascinating and evolving field in modern statistical science, with the potential to make significant contributions to biomedical applications. Th…
A Mixed Model Approach for Estimating Regional Functional Connectivity from Voxel-level BOLD Signals
Ruobin Liu, Chao Zhang, Chau Tran +3
Resting-state brain functional connectivity quantifies the synchrony between activity patterns of different brain regions. In functional magnetic resonance imaging, each region com…
Family-wise error rate control in Gaussian graphical model selection via Distributionally Robust Optimization
Chau Tran, Pedro Cisneros-Velarde, Sang-Yun Oh +1
Recently, a special case of precision matrix estimation based on a distributionally robust optimization (DRO) framework has been shown to be equivalent to the graphical lasso. From…
Fréchet single index models for object response regression
Aritra Ghosal, Wendy Meiring, Alexander Petersen
With the increasing availability of non-Euclidean data objects, statisticians are faced with the task of developing appropriate statistical methods for their analysis. For regressi…
Wasserstein Autoregressive Models for Density Time Series
Chao Zhang, Piotr Kokoszka, Alexander Petersen
Data consisting of time-indexed distributions of cross-sectional or intraday returns have been extensively studied in finance, and provide one example in which the data atoms consi…
