Dear List,

I am trying to understand the literature of fitting Markov Chain model
to daily Rainfall data. I need to know how can i calculate the observed
and expected frequencies of different lengths of "Wet Spell", "Dry
Spell", "Wet-Dry cycle", and "Dry-Wet cycle" (a day with greater or
equal to 0.1 mm of precipitation is being considered as a wet day) for
the rainfall data, such as the following:
http://www.angelfire.com/ab5/get5/raw.data.txt
where observations are for each day during 1989-2002 measured in mm.

Any direction, suggestion, references, analysis tips regarding this
will be highly appreciated.

Thank you for your time.
