Hi, Is there an easy way to generate data with temporal autocorrelation? I want to generate data with something like rnorm where I can specify the mean, variance and time lag.

See arima.sim() in the ts package; also it seems there is another arima.sim() in the boot package, but I don't know wheter it is the same. best, vito ----- Original Message ----- From: "Andy Bunn" <abunn59715 at earthlink.net> To: <r-help at stat.math.ethz.ch> Sent: Thursday, October 10, 2002 8:16 AM Subject: [R] Generating AR1 data> Hi, Is there an easy way to generate data with temporal autocorrelation?
