Geostatistical modeling of positive-definite matrices: An application to diffusion tensor imaging
BIOMETRICS.
author keywords: Cholesky decomposition; diffusion tensor imaging; geostatistical modeling; positive‐ definite matrix; spatial random fields; spatial Wishart process
MeSH headings : Computer Simulation; Diffusion Tensor Imaging; Normal Distribution; Stochastic Processes
TL;DR:
An approximation method is proposed to obtain a feasible Cholesky decomposition model, which is shown to be asymptotically equivalent to the spatial Wishart process model and to produce reliable inference and improved performance, compared to other methods.

Determination of vadose zone and saturated zone nitrate lag times using long-term groundwater monitoring data and statistical machine learning
HYDROLOGY AND EARTH SYSTEM SCIENCES, 25(2), 811–829.
Contributors: M. Wells *, T. Gilmore*, N. Nelson n , A. Mittelstet * & J. Böhlke *
TL;DR:
The statistical machine learning model results are consistent with previous observations of relatively high-water fluxes and short transit times for water and nitrate in the aquifer and indicate a sharp threshold where high groundwater nitrate concentrations are mostly associated with total travel times of seven years or less.

Quantifying uncertainty cascading from climate, watershed, and lake models in harmful algal bloom predictions
SCIENCE OF THE TOTAL ENVIRONMENT, 759.
author keywords: Integrating models; Error analysis; Monte Carlo; Forecasting
MeSH headings : Canada; Harmful Algal Bloom; Lakes; Phosphorus; Uncertainty
TL;DR:
This study integrated an ensemble of four climate models, three watershed models, and four HAB models to show that climate impacts on watershed processes are likely to lead to reductions in future loading, assuming land use and watershed management practices are unchanged.

A spatial Bayesian semiparametric mixture model for positive definite matrices with applications in diffusion tensor imaging
CANADIAN JOURNAL OF STATISTICS-REVUE CANADIENNE DE STATISTIQUE, 49(1), 129–149.
author keywords: Diffusion tensor imaging; inverse Wishart distribution; matrix variate; positive definite matrix; spatial statistics
TL;DR:
A matrix‐variate Bayesian semiparametric mixture model is proposed, where the p.d. matrices are distributed as a mixture of inverse Wishart distributions, with the spatial dependence captured by a Markov model for the mixture component labels.

Exploring nutrient and light limitation of algal production in a shallow turbid reservoir
ENVIRONMENTAL POLLUTION, 269.
author keywords: Cyanobacteria; Eutrophic reservoir; Nutrients; Mixing; Modeling
MeSH headings : Bayes Theorem; Environmental Monitoring; Eutrophication; Jordan; Lakes; North Carolina; Nutrients; Phosphorus / analysis
TL;DR:
It is indicated that nutrient reductions, rather than changes in mixing or background turbidity, are critical to controlling cyanobacteria in a shallow eutrophic freshwater system.

Chromophoric dissolved organic matter composition and load from a coastal river system under variable flow regimes
SCIENCE OF THE TOTAL ENVIRONMENT, 760.
author keywords: Flow regime; Coastal watershed; Chromophoric dissolved organic matter (CDOM); Parallel factor analysis (PARAFAC); Pulse and shunt; Organic matter
TL;DR:
It is suggested that similar coastal watersheds in SE USA or elsewhere may contribute substantial amounts of reactive CDOM to the estuaries during high flow conditions and can have negative water quality implications for the coastal C dynamics.
