We consider modeling of angular or directional data viewed as a linear variable wrapped onto a unit circle. In particular, we focus on the spatio-temporal context, motivated by a collection of wave directions obtained as computer model output developed dynamically over a collection of spatial locations. We propose a novel wrapped skew Gaussian process which enriches the class of wrapped Gaussian process. The wrapped skew Gaussian process enables more flexible marginal distributions than the… 
Likelihood-based inference for multivariate space-time wrapped-Gaussian fields
A wrapped-Gaussian field is proposed to model directions in a multivariate spatial or spatio-temporal context and the approach outperforms the analytical and computational limitations of full likelihood, because it works with the marginal bivariate distributions of the random field.
CircSpaceTime: an R package for spatial and spatio-temporal modelling of circular data
CircSpaceTime is the only R package, currently available, that implements Bayesian models for spatial and spatio-temporal interpolation of circular data, and the proposed models are cast as hierarchical, with fitting and inference within a Bayesian framework.
CircSpaceTime: an R package for spatial and spatio-temporal modeling of Circular data
The proposed models are cast as hierarchical, with fitting and inference within a Bayesian framework, and the implementation of the proposed models is considerably improved on the simple routines adopted in the research papers.
A smoothing spline model for multimodal and skewed circular responses: Applications in meteorology and oceanography
The analysis of circular data is the main subject in many disciplines, such as meteorology and oceanography. In this article, we introduce a new multimodal skew‐circular model as an extension of the
Hidden Markov model for discrete circular–linear wind data time series
This work deals with a bivariate time series of wind speed and direction with a non-parametric Bayesian hidden Markov model, introducing a new emission distribution suitable to model the data, based on the invariant wrapped Poisson, the Poisson and the hurdle density.
Recent advances in directional statistics
This paper provides a review of the many recent developments in the field since the publication of Mardia and Jupp (1999), still the most comprehensive text on directional statistics, and considers developments for the exploratory analysis of directional data.
Nonparametric estimation of circular trend surfaces with application to wave directions
In oceanography, modeling wave fields requires the use of statistical tools capable of handling the circular nature of the data measurements. An important issue in ocean wave analysis is the study of
Distributions-oriented wind forecast verification by a hidden Markov model for multivariate circular–linear data
This work proposes a comprehensive model-based inferential approach to investigate the ability of the WRF system to forecast the local wind speed and direction allowing different performances for unknown weather regimes, and provides useful insights on the performance of WRF forecasts in relation to different combinations of windspeed and direction.
Goodness-of-fit tests for parametric regression models with circular response
Testing procedures for assessing a parametric regression model with circular response and $\mathbb{R}^d$-valued covariate are proposed and analyzed in this work both for independent and for spatially


Spatio-temporal circular models with non-separable covariance structure
This work accommodates covariates, implements full kriging and forecasting, and also allows for a nugget which can be time dependent, within a Bayesian framework, to facilitate Markov chain Monte Carlo model fitting.
Modeling Space and Space-Time Directional Data Using Projected Gaussian Processes
The contribution is to develop a fully model-based approach to capture structured spatial dependence for modeling directional data at different spatial locations, and builds a projected Gaussian spatial process, induced from an inline bivariate Gaussia spatial process.
Spatial analysis of wave direction data using wrapped Gaussian processes
A model-based approach to handle periodic data in the case of measurements taken at spatial locations, anticipating structured dependence between these measurements, and formulates a wrapped Gaussian spatial process model for this setting.
Bayesian Analysis of Circular Data Using Wrapped Distributions
Circular data arise in a number of different areas such as geological, meteorological, biological and industrial sciences. Standard statistical techniques can not be used to model circular data due

We consider problems of inference for the wrapped skew-normal distribution on the circle. A centered parametrization of the distribution is introduced, and simulation used to compare the performance
On spatial skew‐Gaussian processes and applications
In many applications, observed spatial variables have skewed distributions. It is often of interest to model the shape of the skewed marginal distributions as well as the spatial correlations. We

A New Spatial Skew-Normal Random Field Model
Skewness is often present in a wide range of geostatistical problems, and modeling it in the spatial context remains a challenging problem. In this article, we propose and study a new class of

A multivariate hidden Markov model that includes features of the data within a single framework, associated with easily interpretable components of large-scale and small-scale spatial variation, and provides a parsimonious representation of the sea surface in terms of alternating environmental states.
