Time refers to the coefficient for the linear term, Time2 refers to the coefficient for the squared term and Time3 refers to the coefficient for the cubed term. The parameter estimates show that there is significant variation among individuals intercepts (I), slopes (S, time) and the covariance between slopes and intercepts (COVI,S).
