Modelling longitudinal polytomous animal data using Bayesian hierarchical models
Maria LetÃcia Salvador, Gabriel Rodrigues Palma, Mariana Coelly Modesto Santos Tavares +2
The analysis of longitudinal categorical data can be complex and unfeasible due to the number of parameters involved, characterised by overparameterisation leading to model non-con…

João César Reis Alves, Gabriel Rodrigues Palma, Idemauro Antonio Rodrigues de Lara
Studies involving sensory analysis are essential for evaluating and measuring the characteristics of food and beverages, including consumer acceptance of samples. For various produ…
Diagnosing overdispersion in longitudinal analyses with grouped nominal polytomous data
Maria LetÃcia Salvador, Gabriel Rodrigues Palma, Rafael de Andrade Moral +1
Experiments in Agricultural Sciences often involve the analysis of longitudinal nominal polytomous variables, both in individual and grouped structures. Marginal and mixed-effects…
Beta regression mixed model applied to sensory analysis
João César Reis Alves, Gabriel Rodrigues Palma, Idemauro Antonio Rodrigues de Lara
Sensory analysis is an important area that the food industry can use to innovate and improve its products. This study involves a sample of individuals who can be trained or not to…
