...-------------- End R-code & output -------------------------------- I cannot figure out how to restrict RHO1 = 0, while allowing estimation of RHO2. Maybe an answer lies in specifying a different ``position vector'' other than the default: corARMA(..., form = ~ 1 | Subject ...). (See p226 of Pinheiro & Bates, 2000 for explanation of a position vector.) But I'm not totally sure if I understand the position vector and I know I don't know how it works in R. Then again, there is likely a completely different way to solve this problem. Any help will be appreciated! Reid
