In this article, the bimatrix variate beta Type IV distribution is derived from
independent Wishart distributed matrix variables. We explore specific properties of
this distribution which is then used to derive the exact expressions of the densities of
the product and ratio of two dependent Wilks’s statistics and to define the bimatrix
Kummer-beta Type IV distribution.
In Statistical Process Control (SPC) there exists a need to model the runlength
distribution of a Q-chart that monitors the process mean when measurements
are from an exponential distribution with an unknown parameter. ...
