  12. Data that may contain periodic components are often best characterized
  13. by the use of circular distributions.  These are suitable for interval
  14. scales of measurement where there is no non-arbitrary zero point and no
  15. non-arbitrary high/low values.  Observations with respect to direction,
  16. time-of-day, day-of-year, and day-of-lunar_cycle ( and in some cultural
  17. settings day-of-week) are commonly described using circular distributions.
  18. Zar[, J.H. (1984) Biostatistical Analysis, 2nd ed., Prentice-Hall]
  19. provides a good introduction to the use of curcular distributions in
  20. chapters 24 and 25.
