Parameters for Closed Jackson Process. The convolution f g of two real-valued functions g and h on Z+ is defined
From these distributions, one can obtain means, variances, covariances, and other items of interest such as expected costs for the process. In particular, show that the mean number of items in a sector J in equilibrium is
