Dear helpers, I am wondering if I can use the growth package to fit continuous ARMA time series. To be specific, y <- arima.sim(model=list(ar=c(1.7,-0.8)),n=100) How do I use carma to fit y if possible? The package is for longitudinal data but I suspect I can use it for my problem. I looked at the help file without success. Thanks for any ideas. -- Zhu Wang Statistical Science Department Southern Methodist University Phone: (214)768-2453 Fax: (214)768-4035 Email: zhuw at mail.smu.edu
