Conceptualizing and Measuring Appetite Self-Regulation Phenotypes and Trajectories in Childhood: A Review of Person-Centered Strategies

open access: yesFrontiers in Nutrition, 2021
This review uses person-centered research and data analysis strategies to discuss the conceptualization and measurement of appetite self-regulation (ASR) phenotypes and trajectories in childhood (from infancy to about ages 6 or 7 years). Research that is

A family of mixture models for biclustering [PDF]

open access: yesStatistical Analysis and Data Mining: The ASA Data Science Journal, 2021
AbstractBiclustering is used for simultaneous clustering of the observations and variables when there is no group structure known a priori. It is being increasingly used in bioinformatics, text analytics, and so on. Previously, biclustering has been introduced in a model‐based clustering framework by utilizing a structure similar to a mixture of factor

A Bayesian latent mixture model approach to assessing performance in stock-flow reasoning

open access: yesJudgment and Decision Making, 2017
People often perform poorly on stock-flow reasoning tasks, with many (but not all) participants appearing to erroneously match the accumulation of the stock to the inflow – a response pattern attributed to the use of a “correlation heuristic”. Efforts to

flexCWM: A Flexible Framework for Cluster-Weighted Models

open access: yesJournal of Statistical Software, 2018
Cluster-weighted models (CWMs) are mixtures of regression models with random covariates. However, besides having recently become rather popular in statistics and data mining, there is still a lack of support for CWMs within the most popular statistical ...

Testing for Homogeneity in Mixture Models [PDF]

open access: yes, 2016
Statistical models of unobserved heterogeneity are typically formalized as mixtures of simple parametric models and interest naturally focuses on testing for homogeneity versus general mixture alternatives.

Local mixture models of exponential families [PDF]

open access: yes, 2007
Exponential families are the workhorses of parametric modelling theory. One reason for their popularity is their associated inference theory, which is very clean, both from a theoretical and a computational point of view.

Sphinx: a Colluder-Resistant Trust Mechanism for Collaborative Intrusion Detection

open access: yesIEEE Access, 2018
The destructive effects of cyber-attacks demand more proactive security approaches. One such promising approach is the idea of collaborative intrusion detection systems (CIDSs).

Optimal transport for Gaussian mixture models [PDF]

open access: yes, 2018
We present an optimal mass transport framework on the space of Gaussian mixture models, which are widely used in statistical inference. Our method leads to a natural way to compare, interpolate and average Gaussian mixture models.

Computational aspects of N-mixture models [PDF]

open access: yes, 2014
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).

How to fit models of recognition memory data using maximum likelihood.

open access: yesInternational Journal of Psychological Research, 2010
The aim of this paper is to provide an introductory tutorial to how to fit different models of recognition memory using maximum likelihood estimation. It is in four main parts.
