variance( alpha, beta ) Returns the variance of a beta distribution with parameters alpha (first shape parameter) and beta (second shape parameter). var v = variance( 1.0, 1.0 ); // returns ~0.083 v = variance( 4.0, 12.0 ); // returns ~0.011 v = variance( 8.0, 2.0 ); // returns...

Beta—binomialDirichletmultinomialanalysisofvarianceThe beta–binomial distribution is reported in literature as a useful generalization of the binomial in case of heterogeneous binomial sampling. An extra model parameter is introduced to accommodate for extra–binomial variation. Some additions to results ...

On the robustness of the modified beta distribution for acceptance sampling in statistical quality control The purpose of this article is to examine the robustness of the modified Beta distribution as a probability distribution of lot fraction defectives in Baye... HL Lee,G Tagaras - 《Naval Rese...
In this article, joint mean and variance beta regression models are proposed. The proposed models are fitted by applying the Bayesian method and assuming normal prior distribution for the regression parameters. An analysis of synthetic and real data is included, assuming the proposed model, together...
Note that c2 is a function of 1 / n and h may or may not depend on the parameters of the underlying distribution. Recall that h may be a positive or a negative value. For the Beta(α,1)-distribution, h>0 when α is less than approximately 34.58 whereas h<0 for larger values of...

The previous post looked at an application of the beta-binomial distribution. The probability mass function for a beta-binomial with parameters n, a, and b is given by The mean μ and the variance σ² are given by Solving for a and b to meet a specified mean and variance appears at...
The second approach uses the first and second moments of the intraclass correlation coefficient estimate in combination with a Beta distribution. Both approaches are based on the restricted maximum likelihood estimates for the variance components involved. Simulation studies are conducted to examine the ...
