## What is/are Simple Step Stress?

Simple Step Stress - In simple step-stress models based on exponential distributions, the distributions of the MLEs are commonly obtained using the moment generating function.^{[1]}In this paper, we mainly consider the inference of a simple step-stress model based on a complete sample, when the stress changes after a prefixed number of failures.

^{[2]}This paper considers simple step-stress accelerated life tests (SSALTs) for one-shot devices.

^{[3]}In this paper, we considered the inference problem on simple step-stress accelerated life test data from one-parameter exponential distribution under type-I censored ordered ranked set sample with cumulative exposure model.
