Abstract

Applications of optimal matching analysis in the social sciences are typically based on sequences of specific social statuses that model the residential, familial, or occupational trajectories of individuals. Despite the broadly recognized interdependence of these statuses, few attempts have been made to systematize the ways in which optimal matching analysis should be applied multidimensionally, i.e., in an approach that takes into account multiple trajectories simultaneously. Based on methods pioneered in the field of bioinformatics, this article proposes the method of multichannel sequence analysis (MCSA), which simultaneously extends the usual optimal matching analysis (OMA) to multiple life spheres. Using data from the Swiss household panel (SHP), we examine the types of trajectories obtained using MCSA. We find that MCSA offers an alternative to the sole use of ex-post sum of distance matrices by locally aligning distinct life trajectories simultaneously. Moreover, MCSA reduces the complexity of the results without making them less informative, it is more robust to noise in the data, and it provides more reliable alignments than two independent OMAs.

Keywords: optimal matching, multidimensional sequence analysis, individual life trajectories, life course
