discrete autoregressive model source codes using Pearson type v distribution

discrete autoregressive model is a mathematical model which is based on Markovian model known as DAR (1) model DAR (1) process is a Markov Chain with discrete state space S and transition matrix : *P = ρ I + (1-ρ) *Where ρ is a autocorrelation coefficient, I is the identity matrix and *Q* is a matrix with Qij*= π (j)* for *i,j ? S *since there is no therm to attach the file for more information I refer to bellow paper: "A new model for video traf?c originating from multiplexed MPEG-4 videoconference streams"
