Interpretation summary for Distribution Overview Plot (Right Censoring)

Use Distribution Overview Plot (Right Censoring) to do one of the following:
  • Select a distribution and then view four graphs—probability plot, probability density function, survival plot, and hazard plot—based on this distribution.
  • Not select a distribution and use a nonparametric method to view up to two graphs—survival plot and hazard plot.

These graphs provide different views of the distribution of your data.

Data description

A reliability engineer studies the failure rates of engine windings of turbine assemblies to determine the times at which the windings fail. At high temperatures, the windings might decompose too fast.

The engineer records failure times for the engine windings at 80° C and 100° C. However, some of the units must be removed from the test before they fail. Therefore, the data are right censored. The engineer uses Distribution Overview Plot (Right Censoring) to fit a lognormal distribution to the data and to visually assess the survival and failure rates over time.
