Abstract
This paper deals with the problem of evaluating dissimilarities between trajectories in a three-way longitudinal data set (a set of multiple time series). The dissimilarity between trajectories is defined as a conic combination of the dissimilarities between trends, velocities and accelerations of the pair of trajectories. The coefficients of the linear combination are estimated maximizing its variance. The proposed methodology is applied on a real data set to classify trajectories of Italian regions by their employment dynamic.
