Comparison of Criteria for Choosing the Number of Classes in Bayesian Finite Mixture Models. [PDF]

open access: yesPLoS ONE, 2017
Identifying the number of classes in Bayesian finite mixture models is a challenging problem. Several criteria have been proposed, such as adaptations of the deviance information criterion, marginal likelihoods, Bayes factors, and reversible jump MCMC ...

lclogit2: An enhanced command to fit latent class conditional logit models

open access: yesThe Stata Journal, 2020
In this article, I describe the lclogit2 command, an enhanced version of lclogit (Pacifico and Yoo, 2013, Stata Journal 13: 625–639). Like its predecessor, lclogit2 uses the expectation-maximization algorithm to fit latent class conditional logit (LCL ...

Latent Class-Conditional Noise Model

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2023
Learning with noisy labels has become imperative in the Big Data era, which saves expensive human labors on accurate annotations. Previous noise-transition-based methods have achieved theoretically-grounded performance under the Class-Conditional Noise model (CCN).

Conditional Image-to-Video Generation with Latent Flow Diffusion Models [PDF]

open access: yesComputer Vision and Pattern Recognition, 2023
Conditional image-to-video (cI2V) generation aims to synthesize a new plausible video starting from an image (e.g., a person's face) and a condition (e.g., an action class label like smile).

Partial identifiability of restricted latent class models [PDF]

open access: yes, 2018
Latent class models have wide applications in social and biological sciences. In many applications, pre-specified restrictions are imposed on the parameter space of latent class models, through a design matrix, to reflect practitioners' diagnostic ...

Recommended Practices in Latent Class Analysis Using the Open-Source R-Package tidySEM

open access: yesStructural Equation Modeling: A Multidisciplinary Journal, 2023
Latent class analysis (LCA) refers to techniques for identifying groups in data based on a parametric model. Examples include mixture models, LCA with ordinal indicators, and latent class growth analysis. Despite its popularity, there is limited guidance

Latent Trajectories of Subjective Well-Being: An Application of Latent Growth Curve and Latent Class Growth Modeling

open access: yesInternational Journal of Contemporary Educational Research, 2023
This study proposed a three-stage measurement model utilizing the Latent Growth Curve Modeling and Latent Class Growth Analysis. The measurement model was illustrated using repeated data collected through a four-week prospective study tracking the ...

Identifiability of restricted latent class models with binary responses [PDF]

open access: yes, 2016
Statistical latent class models are widely used in social and psychological researches, yet it is often difficult to establish the identifiability of the model parameters.
