A comprehensive multi-state conditional occupancy model for evaluating interactions of non-native and native species

open access: yesFrontiers in Ecology and Evolution, 2023
A major challenge in ecology is disentangling interactions of non-native, potentially invasive species on native species. Conditional two-species occupancy models examine the effects of dominant species (e.g., non-native) on subordinate species (e.g ...

Non-Stationary Flood Discharge Frequency Analysis in West Africa

open access: yesGeoHazards, 2023
With climate change and intensification of the hydrological cycle, the stationarity of hydrological variables is becoming questionable, requiring appropriate flood assessment models. Frequency analysis is widely used for flood forecasting.

A case-based method of selecting covariates for digital soil mapping

open access: yesJournal of Integrative Agriculture, 2020
Selecting a proper set of covariates is one of the most important factors that influence the accuracy of digital soil mapping (DSM). The statistical or machine learning methods for selecting DSM covariates are not available for those situations with ...

Modeling Landscape Use for Ungulates: Forgotten Tenets of Ecology, Management, and Inference

open access: yesFrontiers in Ecology and Evolution, 2020
Modeling landscape use (i.e., estimating the probability or relative probability of use, occurrence, or selection in a given area and time) by ungulates is an increasingly common and important practice in research and management.

Optimal Design of a Reliability Experiment Based on the Wiener Degradation Model under Limitations of the Degradation Index

open access: yesEngineering Proceedings, 2023
There are many degradation models that are used in reliability analyses. The Wiener degradation model is the most popular across different applications. In this paper, we propose an approach for searching for an optimal design on the basis of the Wiener ...

Mixture Rasch Model with Main and Interaction Effects of Covariates on Latent Class Membership

open access: yesInternational Journal of Assessment Tools in Education, 2019
Covariateshave been used in mixture IRT models to help explain why examinees are classedinto different latent classes. Previous research has considered manifestvariables as covariates in a mixture Rasch analysis for prediction of groupmembership.

No Time Dependence of Ciprofloxacin Pharmacokinetics in Critically Ill Adults: Comparison of Individual and Population Analyses

open access: yesPharmaceutics, 2021
The aim of this prospective PK study was to evaluate the pharmacokinetics of ciprofloxacin dosed within the first 36 h (early phase) and after 3 days of treatment (delayed phase) using individual and population PK analysis. The secondary aim of the study

ETAS Space–Time Modeling of Chile Triggered Seismicity Using Covariates: Some Preliminary Results

open access: yesApplied Sciences, 2021
Chilean seismic activity is one of the strongest in the world. As already shown in previous papers, seismic activity can be usefully described by a space–time branching process, such as the ETAS (Epidemic Type Aftershock Sequences) model, which is a ...

Comparison of Single-Trait and Multi-Trait Genome-Wide Association Models and Inclusion of Correlated Traits in the Dissection of the Genetic Architecture of a Complex Trait in a Breeding Program

open access: yesFrontiers in Plant Science, 2022
Unknown genetic architecture makes it difficult to characterize the genetic basis of traits and associated molecular markers because of the complexity of small effect quantitative trait loci (QTLs), environmental effects, and difficulty in phenotyping ...
