Stochastic Processes with Modified Lognormal Distribution Featuring Flexible Upper Tail
Dionissios T. Hristopulos, Anastassia Baxevani, Giorgio Kaniadakis
Asymmetric, non-Gaussian probability distributions are often observed in the analysis of natural and engineering datasets. The lognormal distribution is a standard model for data w…
Spatial data modeling by means of Gibbs Markov random fields based on a generalized planar rotator model
Milan Žukovič, Dionissios T. Hristopulos
We introduce a Gibbs Markov random field for spatial data on Cartesian grids which is based on the generalized planar rotator (GPR) model. The GPR model generalizes the recently pr…
Space-Time Covariance Functions based on Linear Response Theory and the Turning Bands Method
Dionissios T. Hristopulos, Ivi C. Tsantili
The generation of non-separable, physically motivated covariance functions is a theme of ongoing research interest, given that only a few classes of such functions are available. W…
Space-Time Models based on Random Fields with Local Interactions
Dionissios T. Hristopulos, Ivi C. Tsantili
The analysis of space-time data from complex, real-life phenomena requires the use of flexible and physically motivated covariance functions. In most cases, it is not possible to e…
