BreakdownTimes {NPIstats}

Breakdown times of units from two groups

Description

We consider a data set used by Nelson (1982, p.462), which gives the breakdown times of units from 6 different groups. In this data set, only the first two groups are used to illustrate the NPI method for pairwise comparison with tails termination. Both groups consist of 10 observations. The first unit of group X has a reported breakdown time of 0.00, we interpret this as a very small but positive breakdown time.
