geyser


A version of the eruptions data from the ``Old Faithful'' geyser in
Yellowstone National  Park,  Wyoming. This version comes from
Azzalini and Bowman (1990) and is of continuous measurement from 
1st August to  15th August  1985. <p></p><p>Some nocturnal duration measurements were coded as 2, 3 or 4 minutes,
having originally been described as `short', `medium' or `long'.
