Modelling and detecting mild and gross anomalies in circular data via double-contaminated models
Antonio Punzo, Andriëtte Bekker, Arno Otto +2
In this paper, we propose a model-based framework to robustify inference for circular data in the presence of anomalous observations, distinguishing between mild and gross anomalie…
Does wind affect the orientation of vegetation stripes? A copula-based mixture model for axial and circular data
Marco Mingione, Francesco Lagona, Priyanka Nagar +4
Motivated by a case study of vegetation patterns, we introduce a mixture model with concomitant variables to examine the association between the orientation of vegetation stripes a…
A dependent circular-linear model for multivariate biomechanical data: Ilizarov ring fixator study
Priyanka Nagar, Andriette Bekker, Mohammad Arashi +2
Biomechanical and orthopaedic studies frequently encounter complex datasets that encompass both circular and linear variables. In most cases the circular and linear variables are (…
Directional Gaussian spatial processes for South African wind data
Jacobus S. Blom, Priyanka Nagar, Andriette Bekker
Accurate wind pattern modelling is crucial for various applications, including renewable energy, agriculture, and climate adaptation. In this paper, we introduce the wrapped Gaussi…
