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.

A stabilized moment estimator for the beta-binomial distribution.

Biometrics, 1987
The beta-binomial distribution has been proposed as a model for the incorporation of historical control data in the analysis of rodent carcinogenesis bioassays. Low spontaneous tumor incidences along with the small number and sizes of historical control groups combine to make the moment and maximum likelihood estimates of the beta-binomial parameters ...

Maximum Likelihood Estimation for the Beta-Binomial Distribution and an Application to the Household Distribution of the Total Number of Cases of a Disease

Biometrics, 1973
In part I, maximum likelihood (ML) estimation for the beta-binomial distribution (BBD) is considered. The BBD can be used as a model for the incidence in households of noninfectious disease. Typically households in which there are no cases of disease will not be included in the data. It is then necessary to fit a truncated BBD.

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.

Using the Beta-Binomial Distribution to Describe Aggregated Patterns of Disease Incidence

Phytopathology, 1993
We discuss the use of the beta-binomial distribution for the description of plant disease incidence data, collected on the basis of scoring plants as either «diseased» or «healthy». The beta-binomial is a discrete probability distribution derived by regarding the probability of a plant being diseased (a constant in the binomial distribution) as a beta ...

The two-dimensional beta binomial distribution

Statistics & Probability Letters, 2011
We introduce the two-dimensional beta binomial distribution to describe correlated counts data. Properties of the distribution are explored and in an example the distribution is used to describe a set of orthodontic data.
