## 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 have originally been described as ‘short’, ‘medium’ or ‘long’ and are given as interval censored observations in this version of the dataset.

### Usage

    geyser

### Format

A data frame with 299 observations on 2 variables.

`duration` | Surv | Eruption time in mins
`waiting` | numeric | Waiting time for this eruption

### Note

Variable `duration` was converted to a `Surv` object for representing interval censored nocturnal observations.
