Fig. 2From: Reliability analysis using an exponential power model with bathtub-shaped failure rate function: a Bayes studyPlot of the failure rate function h(t) with \(\alpha =1\) and \(\gamma \) changing from 0.4 to 1.75. It is evident that the hazard function for \(\gamma <1\) assumes a bathtub shape while for \(\gamma \ge 1\), it increases exponentiallyBack to article page
