Description

A bivariate data set obtained from the Old Faithful Geyser, containing the eruption length and the length of the previous eruption for 271 eruptions of this geyser in minutes.

Usage

data(geyser2)

Format

Eruption length: The eruption length in minutes.
Previous eruption length: The length of the previous eruption in minutes.

Source

This particular data structure can be obtained by applying the following code to the "Old Faithful Geyser" (faithful data set (Härdle 1991) in the package datasets):
f1 <- faithful[,1]
geyser2 <- cbind (f1[-length(f1)], f1[-1])
colnames (geyser2) <- c("Eruption length",
"Previous eruption length")
