Characterization-based approach for construction of goodness-of-fit test for Lévy distribution
Žikica Lukić and Bojana Milošević

2023-12-25
The Lévy distribution, together with the Normal and Cauchy distribution, belongs to the class of stable distributions, and it is among the only three distributions for which the density can be derived in a closed form. The density function of the two-parameter Lévy distribution is expressed as…

Circular data, i.e., data defined on the unit circle, can be found in many areas of science. The unique nature of these data means that conventional methods for non-circular data are not valid for these. At the same time, advances in geographical information and global positioning systems have…

Populations of Unlabeled Networks: Graph Space Geometry and Generalized Geodesic Principal Components
Anna Calissano, Aasa Feragen and Simone Vantini

Sets of graphs arise in many different applications, from medicine to finance, from urban planning to social science. Analysing sets of graphs is far from trivial as they are strongly non Euclidean data type. There are two main sets of graphs: […] Unlabelled graphs poses high challenges from…

Stochastic Fluid Dynamics
2023-10-14
Stochastic Fluid Dynamics Wednesday, November 15th, 6:00 PT / 9:00 ET / 15:00 CET The study of fluid dynamics equations with white forcing is a classical topic in SPDEs and ergodic theory. Recently a new wave of interest, with a shift in focus towards transport noise, has risen, due to its…

Locally Sparse Functional Regression
Mauro Bernardi, Antonio Canale and Marco Stefanucci
/
2023-10-09
In this post we present a new estimation procedure for functional linear regression useful when the regression surface – or curve – is supposed to be exactly zero within specific regions of its domain. Our approach involves regularization techniques, merging a B-spline representation of the unknown…
