timesoffailure: successive failure times

In MixtureInf: Inference for Finite Mixture Models

Description

The data set contains the times of successive failures for the air conditioning system of each member in a fleet of 13 Boeing 720 jet aircrafts. The data frame has 213 rows and 1 column.

Usage

#Load this data set for subsequent analysis:
data(timesoffailure)

Format

This data frame contains one column,

x: pooled failure times about 213 observations.
