+models.  It contains

+@enumerate
+@item an orthogonal set of deviance measures for absolute, relative and
+  ordinal scale and
+@item approaches accounting for time shifts.
+@end enumerate
+
+The first approach transforms time to take time delays and speed differences
+into account.  The second divides the time series into interval units
+according to their main features and finds the @dfn{longest common
+subsequence} (LCS) using a dynamic programming algorithm.")
