Good afternoon Using R 2.9.2 on a machine running Windows XP I have a longitudinal data set, with data on schools and their test scores over a four year period. I have centered year, and run the following m1.mod1 <- lme(fixed = math_1 ~ I(year-2007.5)*TFC_, data = long, random = ~I(year-2007.5)|schoolnum, na.action = "na.omit") where

...data=Grouped.Data, + fixed=Asym + xmid + scal ~ Est.LC, + random=Asym + xmid + scal ~ 1, + start=c(105,-5, 4,-5,30,-5)) > Sum.Result.NLME <- summary(Result.NLME) > > round(Sum.Result.NLME$corFixed, 2) Asym.(Intercept) Asym.Est.LC xmid.(Intercept) xmid.Est.LC scal.(Intercept) scal.Est.LC Asym.(Intercept) 1.00 -0.93 0.55 -0.51 0.50 -0.46 Asym.Est.LC -0.93 1.00...
