Multivariate digamma distribution

Annals of the Institute of Statistical Mathematics Aims and scope Submit manuscript

Summary

Digamma distributions are extended to multivariate distributions and their properties are examined. The distributions are closely related to multivariate logarithmic series distributions and will be useful when observed frequency data have too long tail to be fitted by a multivariate logarithmic series distribution.
