Optimal Matching Analysis and Life-Course Data: The Importance of Duration

May 13, 2010

Brendan Halpin: Optimal Matching Analysis and Life-Course Data: The Importance of Duration, Sociological Methods Research 2010 38: 365-388.

Brendan HalpinThe optimal matching (OM) algorithm is widely used for sequence analysis insociology. It has a natural interpretation for discrete-time sequences but isalso widely used for life-history data, which are Read the rest of this entry »

Is Optimal Matching Suboptimal?

February 7, 2010

Matissa Hollister Is Optimal Matching Suboptimal? Sociological Methods & Research 2009 38: 235-264.

Optimal matching (OM) is a method for measuring the similarity between pairs of sequences (e.g., work histories). This article discusses two problems with optimal matching. First, the authoridentifies a flaw in OM ‘‘indel costs’’ and proposes a solution Read the rest of this entry »


How Much Does It Cost?: Optimization of Costs in Sequence Analysis of Social Science Data

February 7, 2010

Jacques-Antoine Gauthier, Eric D. Widmer, Philipp Bucher, and Cédric Notredame How Much Does It Cost?: Optimization of Costs in Sequence Analysis of Social Science Data Sociological Methods & Research 2009 38: 197-231.

One major methodological problem in analysis of sequence data is the determination of costs from which distances between sequences are derived. Although this problem is currently not optimally dealt with in the social sciences, it has Read the rest of this entry »
