geyser: 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 H<U+00E4>rdle (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.
