Application of the Beta-Binomial Distribution for Statistical Processing of Student Grades [PDF]
Baikal Research Journal, 2020 Statistical processing of students' grades is used to solve various problems in managing the educational process. Traditional methods of mathematical statistics do not correspond to the properties of student grades. The paper proposes to adapt the IRT models for describing grades to improve the whole process. A model based on beta-binomial distribution

Estimation of habitual intake of infrequently consumed nutrients using the mixture distribution method [PDF]
Frontiers in NutritionBackgroundThe habitual intake of infrequently consumed nutrients typically exhibits a highly skewed distribution, primarily driven by the reported consumption and non-consumption of nutrients in repeated 24-h dietary recalls.

Analysis of distributional variation through multi-scale Beta-Binomial modeling [PDF]
, 2016 Many statistical analyses involve the comparison of multiple data sets collected under different conditions in order to identify the difference in the underlying distributions. A common challenge in multi-sample comparison is the presence of various confounders, or extraneous causes other than the conditions of interest that also contribute to the ...

Characterizing correlations in partial credit speech recognition scoring with beta-binomial distributions [PDF]
JASA Express LettersPartial credit scoring for speech recognition tasks can improve measurement precision. However, assessing the magnitude of this improvement with partial credit scoring is challenging because meaningful speech contains contextual cues, which create correlations between the probabilities of correctly identifying each token in a stimulus.

Heterogeneous model for superdiffusive movement of dense core vesicles in C. elegans [PDF]
Scientific ReportsTransport of dense core vesicles (DCVs) in neurons is crucial for distributing molecules like neuropeptides and growth factors. We studied the experimental trajectories of dynein-driven directed movement of DCVs in the ALA neuron in C.

Hierarchical Generalized Linear Models: The R Package HGLMMM [PDF]
Journal of Statistical Software, 2011 The R package HGLMMM has been developed to fit generalized linear models with random effects using the h-likelihood approach. The response variable is allowed to follow a binomial, Poisson, Gaussian or gamma distribution.
