One area of team support that is often desired is the scoring and ranking of decision alternatives on qualitative/subjective d
In this paper we consider maximum likelihood analysis of generalized growth curve model with the Box-Cox transformation when the covariance matrix has AR(q) dependence structure with grouping variances. The covariance matrix under consideration is S = D s CD s where C is the correlation matrix with
