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 ...

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.

The DISTRIBUTION statement specifies that the Weibull distribution is used for parameter estimation and probability plotting. The PROBPLOT statement requests a probability plot of the data. The ...
