failure_time: Failure Time of Vertical Boring Machine
Description
This dataset contains the failure times (in hours) of a vertical boring machine, used to illustrate the control chart for monitoring the Maxwell distribution parameter.The data was originally reported by Krishna and Malik (2012).
Usage
data("failure_time")
Arguments
Format
A data frame consisted of 8 sample batches each wiht 4 observations.
Details
The failure times in this dataset are organized into 8 subgroups, each containing 4 observations. The failure times are measured in hours. These data are used to construct control charts for monitoring the scale parameter of the Maxwell distribution.
