The Duane plot is a plot of cumulative operating time against the cumulative failure rate on double logarithmic axes. It is often claimed that the power law process, a non‐homogeneous Poisson process with intensity function $\lambda(t)=(\beta/\theta)(t/\theta)^{\beta-1}$ , implies a linear Duane plot. We show that this implication and its converse are false. Copyright © 2002 John Wiley & Sons, Ltd.
