This example compares the use of three-parameter and two-parameter Weibull Q-Q plots for the failure times in months for 48 integrated circuits. The times are assumed to follow a Weibull distribution.
In life and fatique testing, multi-censored samples arise when at various stages of a test, some of the survivors are withdrawn from further observation. Sample specimens which remain after each stage ...
To find an appropriate model for a process distribution, you should consider curves from several distribution families. As shown in this example, you can use the HISTOGRAM statement to fit more than ...
Here’s a way to calculate the reliability for designs with several subsystems. • Weibull plots fit a curve through data, not data to a predetermined distribution’s curve. • After evaluating subsystems ...
Assume that a (possibly censored) sample is available from a population having a Weibull or extreme value distribution, and that a single future observation is to be obtained from the same population.
