Interpretation summary for Distribution ID Plot (Right Censoring)

Use Distribution ID Plot (Right Censoring) to compare the fits of the following distributions: smallest extreme value, Weibull, 3-parameter Weibull, exponential, 2-parameter exponential, normal, lognormal, 3-parameter lognormal, logistic, loglogistic, or 3-parameter loglogistic. Minitab provides both probability plots and goodness-of-fit statistics.

To assess how using different distributions may affect your results, you can also compare the estimates of the percentiles and mean time to failure (MTTF).

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 various temperatures. However, some of the units must be removed from the test before they fail. Therefore, the data are right censored. To select a distribution model for the data collected at 80° C, the engineer uses Distribution ID Plot (Right Censoring.
