Further simulations show ... that this result is quite robust to the speciﬁcation of the linear ACD process. The simulations also indicate that by substituting maximum likelihood estimates for the true values of the parameters, the 95% conﬁdence interval of the lower bound provides a tight conﬁdence band to the true probability distribution function of the process.
