WebIn this chapter, we work with a flexible failure rate based SSALT model with pre-fixed but arbitrarily chosen failure rates at different stress levels. If s1 and s2 are the two stress levels and τis the stress changing time point, it is assumed that the hazard rate of the distribution under the step-stress pattern is as follows: h(t)= WebNov 11, 2013 · The most widely-used cure model is the Mixture Cure Model (MCM) which is also known as the standard cure rate.
