Integrated environmental risk assessment of rare earth elements mixture on aquatic ecosystems
Frontiers in Environmental Science, 2022 Rare Earth elements (REE) have become essential in strategical sectors such as high- and green-technologies. Their increasing use in human activities worldwide leads to anthropogenic REE releases detectable in all compartments of the environment ...

A simulation study of a parametric mixture model of three different distributions to analyze heterogeneous survival data [PDF]
, 2013 In this paper a simulation study of a parametric mixture model of three different distributions is considered to model heterogeneous survival data.Some properties of the proposed parametric mixture of Exponential, Gamma and Weibull are investigated.The ...

The Annals of Mathematical Statistics, 1966 Then a necessary and sufficient condition for x2(H) > x2(0H) to hold for all H E xe is that X2 is convex with respect to xi on T. The inequality is strict for all H E SC for which xi is not constant a.e. [H] on T, if and only if the convexity is everywhere strict; there is equality for all H E SC if and only if X2 is linear with respect to Xi on T.

Identifying Mixtures of Mixtures Using Bayesian Estimation [PDF]
Journal of Computational and Graphical Statistics, 2017 The use of a finite mixture of normal distributions in model-based clustering allows to capture non-Gaussian data clusters. However, identifying the clusters from the normal components is challenging and in general either achieved by imposing constraints on the model or by using post-processing procedures.
