Computational aspects of N-mixture models [PDF]
, 2015 The N-mixture model is widely used to estimate the abundance of a population in the presence of unknown detection probability from only a set of counts subject to spatial and temporal replication (Royle, 2004, Biometrics 60,105–115).

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 ...

Dealing with Label Switching in Mixture Models Under Genuine Multimodality [PDF]
, 2008 The fitting of finite mixture models is an ill-defined estimation problem as completely different parameterizations can induce similar mixture distributions.

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.

Applied Rheology, 2013 A commercial epoxy resin system was tested under several different mixing conditions with viscometer and rheometer apparatuses. In each test, two portions of the same resin, prepared at different times, were mixed and their joint behavior was analysed ...

Mixture models for distance sampling detection functions [PDF]
, 2015 Funding: EPSRC DTGWe present a new class of models for the detection function in distance sampling surveys of wildlife populations, based on finite mixtures of simple parametric key functions such as the half-normal. The models share many of the features
