A new Birnbaum–Saunders distribution and its mathematical features applied to bimodal real-world data from environment and medicine

J Reyes, J Arrué, V Leiva, C Martin-Barreiro - Mathematics, 2021 - mdpi.com
In this paper, we propose and derive a Birnbaum–Saunders distribution to model bimodal
data. This new distribution is obtained using the product of the standard Birnbaum …

How the sampling variances affect the linear predictor of the Fay-Herriot model

L Marcis, MC Pagliarella, R Salvatore - Metron, 2024 - Springer
Abstract The Fay-Herriot model can be seen as a linear mixed-effects model, with known
within-subject variance parameters. These values are given by the sampling variances of …
