r-scans (1-scans)
Purpose: Inspect occurrences of a relatively short “word” (motif) in a long sequence, and determine if they are “randomly” distributed, against the possibilities they are clumped or overdispersed.
Idealizations:
- Occurences of the motif represented as points of the unit interval
- Null hypothesis, coordinates of the points are iid uniform on (0,1)
- Alternative hypotheses not clearly specified
