The beta-binomial model for estimating heritabilities of binary traits

Theoretical and Applied Genetics, 1995
Calculations of individual narrow-sense heritability and family mean heritability of a binary trait in stochastically simulated sib trials in completely randomized block experiments showed that in some situations estimates of "realized" heritabilities obtained from the mixed linear threshold model could be improved by application of a proposed beta ...

A BETA-BINOMIAL MODEL FOR ESTIMATING THE SIZE OF A HETEROGENEOUS POPULATION

Australian <html_ent glyph="@amp;" ascii="&amp;"/> New Zealand Journal of Statistics, 2005
Summary This paper compares the properties of various estimators for a beta-binomial model for estimating the size of a heterogeneous population. It is found that maximum likelihood and conditional maximum likelihood estimators perform well for a large population with a large capture proportion.

The Beta-Binomial SGoF method for multiple dependent tests

Statistical Applications in Genetics and Molecular Biology, 2012
In this paper a correction of SGoF multitesting method for dependent tests is introduced. The correction is based in the beta-binomial model, and therefore the new method is called Beta-Binomial SGoF (or BB-SGoF). Main properties of the new method are established, and its practical implementation is discussed.

Estimating the Parameters of the Beta-Binomial Distribution

Educational and Psychological Measurement, 1979
For some situations the beta-binomial distribution might be used to describe the marginal distribution of test scores for a particular population of examinees. To use this distribution it is necessary to estimate two parameters which characterize the beta-binomial model. One method of estimating these parameters is to approximate the maximum likelihood

Using the beta-binomial distribution for the analysis of biometric identification

2015 IEEE 13th International Symposium on Intelligent Systems and Informatics (SISY), 2015
In this paper we presented a method which could be used in the testing process of biometric devices on the side of users and costumers. The failed events during the biometrical identification are more common than the literature data, however there isn't any standard or widely accepted manual for the examinations.

Unimodal Behavior of the Negative Beta Binomial Distribution

Sigmae, 2015
Neste artigo apresenta-se um estudo sobre o comportamento da distribuição BetaBinomial Negativa em relação a sua moda. Aplica-se este estudo quando essa distribuição é dada através de uma distribuição hipergeométrica equivalente multiplicada pela verossimilhança cada distribuição Binomial Negativa.

Characterization of beta, binomial, and Poisson distributions

IEEE Transactions on Reliability, 1991
Summary: Characterizations of beta, binomial, and Poisson distributions are presented by using conditional expectations. A necessary and sufficient condition is given in terms of the failure rate of each distribution. Some practical applications are presented.

Bayesian Estimation and Prediction for the Beta-Binomial Model

Journal of Business & Economic Statistics, 1987
The beta-binomial distribution, which is generated by a simple mixture model, has been widely applied in the social, physical, and health sciences. Problems of estimation, inference, and prediction have been addressed in the past, but not in a Bayesian framework.
