{title:Description}

{pstd}{cmd:degenne} calculates distances between all pairs of
sequences in the data, using methods based on those proposed by
Degenne et al. (1995), where {it:varlist} is a consecutive set of
variables describing the elements of the sequence. Degenne
distances compare sequences element by element by summing the angle
between the vectors of cumulated duration at each time point.
