A multivariate spatial skew-t process for joint modeling of extreme precipitation indexes
Arnab Hazra, Brian J. Reich, Ana-Maria Staicu
To study trends in extreme precipitation across US over the years 1951-2017, we consider 10 climate indexes that represent extreme precipitation, such as annual maximum of daily pr…
Hierarchical Continuous Time Hidden Markov Model, with Application in Zero-Inflated Accelerometer Data
Zekun Xu, Eric B. Laber, Ana-Maria Staicu
Wearable devices including accelerometers are increasingly being used to collect high-frequency human activity data in situ. There is tremendous potential to use such data to infor…
A semiparametric spatiotemporal Bayesian model for the bulk and extremes of the Fosberg Fire Weather Index
Arnab Hazra, Brian J. Reich, Benjamin A. Shaby +1
Large wildfires pose a major environmental concern, and precise maps of fire risk can improve disaster relief planning. Fosberg Fire Weather Index (FFWI) is often used to measure w…
A nonparametric spatial test to identify factors that shape a microbiome
Susheela P. Singh, Ana-Maria Staicu, Robert R. Dunn +2
The advent of high-throughput sequencing technologies has made data from DNA material readily available, leading to a surge of microbiome-related research establishing links betwee…
Functional Variable Selection for EMG-based Control of a Robotic Hand Prosthetic
Md Nazmul Islam, Jonathan Stallings, Ana-Maria Staicu +3
State-of-the-art robotic hand prosthetics generate finger and wrist movement through pattern recognition (PR) algorithms using features of forearm electromyogram (EMG) signals, but…
Spatial shrinkage via the product independent Gaussian process prior
Arkaprava Roy, Brian J. Reich, Joseph Guinness +2
We study the problem of sparse signal detection on a spatial domain. We propose a novel approach to model continuous signals that are sparse and piecewise smooth as product of inde…
