摘要：Three new distributions on the unit interval [0,1] are introduced which generalize the standard beta distribution. These
distributions involve the Bessel function. Expression is derived
for their shapes, particular cases, and the nth moments.
Estimation by the method of maximum likelihood and Bayes
estimation are discussed. Finally, an application to consumer
price indices is illustrated to show that the proposed
distributions are better models to economic data than one based on
the standard beta distribution.
