Old Faithful Geyser Data

Description

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 August 1 to August 15, 1985.

Some nocturnal duration measurements were coded as 2, 3 or 4 minutes, having originally been described as ‘short’, ‘medium’ or ‘long’.

Usage

Format

A data frame with 299 observations on 2 variables.

duration numeric Eruption time in mins
waiting numeric Waiting time for this eruption

Note

The waiting time was incorrectly described as the time to the next eruption in the original files, and corrected for MASS version 7.3-30.
