simulating a 2-parameter integrated ornstein-uhlenbeck process?

(JASA 1994) "a stochastic model for the analysis of longitudinal aids data." the model they suggest consists of a combination of fixed and random effects, a stochastic process, and measurement error. the 2-parameter IOU process they suggest has cov[W(s), W(t)] = (sigma^2/(2alpha^3)[2alpha min(s,t)+exp(-alpha* t) +exp(-alpha* s)-1 -exp(alpha*|t-s|)). any insight into either fitting the model or simulating a 2-parameter IOU process would be appreciated. thanks, farzad ____________________________________________________________________________________ Be a bette...

* newbie: overhead paging and nbsd
I've looked through the lists and archives for overhead paging and I've seen responses to use nbsd or chan_oss. Does someone have a recipe to follow that shows how to implement overhead paging? best regards, erik
