Hierarchical Dynamic Beta Model
Revstat Statistical Journal, 2016 We develop a hierarchical dynamic Bayesian beta model for modelling a set of time series of rates or proportions. The proposed methodology enables to combine the information contained in different time series so that we can describe a common underlying ...

Beta testing the monkey model [PDF]
Nature Immunology, 2021 Corbett et al. use the rhesus macaque model to evaluate the ability of the mRNA-1273 (Moderna) COVID-19 vaccine to protect against challenge with the antibody-evading Beta variant of SARS-CoV-2. Their key finding is that the vaccine prevents severe lung pathology, principally because it is able to induce a strong enough antibody resistance to overcome ...

Journal of Financial Research, 2019 AbstractWe present a reactive beta model that accounts for the leverage effect and beta elasticity. For this purpose, we derive a correlation metric for the leverage effect to identify the relation between the market beta and volatility changes.

Matrix models for beta ensembles [PDF]
Journal of Mathematical Physics, 2002 This paper constructs tridiagonal random matrix models for general (β>0) β-Hermite (Gaussian) and β-Laguerre (Wishart) ensembles. These generalize the well-known Gaussian and Wishart models for β=1,2,4. Furthermore, in the cases of the β-Laguerre ensembles, we eliminate the exponent quantization present in the previously known models. We further

Zero-Inflated Beta Distribution Regression Modeling
Journal of Agricultural, Biological and Environmental Statistics, 2022 A frequent challenge encountered with ecological data is how to interpret, analyze, or model data having a high proportion of zeros. Much attention has been given to zero-inflated count data, whereas models for non-negative continuous data with an abundance of 0s are lacking.

Transient beta modulates decision thresholds during human action-stopping
NeuroImage, 2022 Action-stopping in humans involves bursts of beta oscillations in prefrontal-basal ganglia regions. To determine the functional role of these beta bursts we took advantage of the Race Model framework describing action-stopping.

Applying black- Scholes model to breakdown beta: growth options and the risk of beta miscalculation [PDF]
Iranian Journal of Finance, 2019 When evaluating companies and investment plans, most analysts use a discount rate that is derived from CAPM models. The beta in these models usually represent risks and opportunities of the relative industry, with almost no attention to the risks that ...
