Bimodal and Multimodal Extensions of the Normal and Skew Normal Distributions
Revstat Statistical JournalA transformation of a density function is introduced to derive two families of continuous densities, the first symmetric and the second not-necessarily symmetric, exhibiting both unimodality and bimodality.

Tests in skew–normal regression models
Communications in Statistics - Simulation and ComputationA skew-normal model is the first option to fit data with presence of skewness. It is also important not to forget the existence of small samples, which can come from experimental studies of areas such as health-related, biology, pharmacology, engineering, etc, and have as one of the most common characteristics the presence of skewness.

A Bayesian model for age at death with unequal adult mortality and cohort effects
GenusThe conventional approach to modeling age at death through parametric models often employs a three-component mixture as a standard. However, recognizing the need to more accurately reflect the diverse trends in old age mortality, this study introduces a ...
