Abstract. The SADI package provides tools for sequence analysis, which focuses on
the similarity and dissimilarity between categorical time series such as
life-course trajectories. SADI's main components are tools to calculate
intersequence distances using several different algorithms, including the
optimal matching algorithm, but it also includes utilities to graph, summarize,
and manage sequence data. It provides similar functionality to the R package
TraMineR and the Stata package SQ but is substantially faster
than the latter.
