Constrained mixtures of generalized normal distributions
Pierdomenico Duttilo, Stefano Antonio Gattone, Alfred Kume
This work introduces a family of univariate constrained mixtures of generalized normal distributions (CMGND) where the location, scale, and shape parameters can be constrained to b…
Rolled Gaussian process models for curves on manifolds
Simon Preston, Karthik Bharath, Pablo Lopez-Custodio +1
Given a planar curve, imagine rolling a sphere along that curve without slipping or twisting, and by this means tracing out a curve on the sphere. It is well known that such a roll…
A branch cut approach to the probability density and distribution functions of a linear combination of central and non-central Chi-square random variables
Alfred Kume, Tomonari Sei, Andrew T. A. Wood
The paper considers the distribution of a general linear combination of central and non-central chi-square random variables by exploring the branch cut regions that appear in the s…
An application of Saddlepoint Approximation for period detection of stellar light observations
Efthymia Derezea, Alfred Kume, Dirk Froebrich
One of the main features of interest in analysing the light curves of stars is the underlying periodic behaviour. The corresponding observations are a complex type of time series w…
A survey for variable young stars with small telescopes: IV -- Rotation Periods of YSOs in IC5070
Dirk Froebrich, Efthymia Derezea, Aleks Scholz +50
Studying rotational variability of young stars is enabling us to investigate a multitude of properties of young star-disk systems. We utilise high cadence, multi-wavelength optical…
Multivariate Max-Stable Processes and Homogeneous Functionals
Enkelejd Hashorva, Alfred Kume
Multivariate max-stable processes are important for both theoretical investigations and various statistical applications motivated by the fact that these are limiting processes, fo…
