R: Air-conditioning data

aircond {gamlss.data} | R Documentation

## Air-conditioning data

### Description

These data, reported by Proschan (1963, Technometrics 5, 375-383), refer to the intervals, in service-hours, between failures of the air-conditioning equipment in a Boeing 720 aircraft. (Proschan reports data on 10 different aircraft. The data from only one of the aircraft is used here. Cox and Snell (1981, Applied Statistics: principles and examples, Chapman and Hall, London) discuss the analysis of the data on all 10 aircraft.) The dataset consists of a single vector of data. They are used in the book ‘Distributions for location, scale and shape: Using GAMLSS in R’ to demonstrate the likelihood function and maximum likelihood estimation.

### Usage

    data("aircond")

### Format

A data frame with 24 observations on the following variable.

`aircond`

  a numeric vector

### Source

The data were taken from the R package `rpanel` where they refer to as `aircon`.
