Waiting time between geyser eruptions
Description
This dataset contains the interval times between the starts of the geyser eruptions on the Old Faithful Geyser in Yellowstone National Park, Wyoming, USA.
Usage
data(geyser)
data(geyserab)
data(geyserh)
data(geyserw)
Format
geyser, geyserh and geyserw include data collected in October 1980. geyser and geyserh were obtained from Table 3 of Härdle (2012), in geyser some repeated data are removed. geyserw was obtained from the Supplementary material of Weisberg (2005). geyserab include data collected in August 1985 from Table 1 in Azzalini and Bowman (1990).
Details
This is a classic example for estimating the density.
