heal.abstract	Engineers in the manufacturing industries have used accelerated test (AT) experiments for many decades, in order to acquire reliability information quickly. The need to extrapolate in both time and the accelerating variables generally necessitates the use of fully parametric models. The past 30 years have seen the development of statistical methods for obtaining results for reliability from degradation data. When an appropriate degradation variable can be measured, degradation data, when properly analyzed, can provide much more information because there are quantitative measurements on all units (not just those that failed). Since many devices fail because of degradation, the degradation process is some type of stochastic process. The first chapter introduces the meaning of the degradation of reliability data and some degradation procedures are referenced briefly. In the second chapter the modeling of the degradation is studied through the Wiener and Markov procedures. The third chapter introduces Gamma procedure. The next chapter analyzes degradation models with covariates and the threshold regression. Methods for the accelerated life tests are presented in the fifth chapter. In the sixth and final chapter, three examples are described and all the previous methods are applied in their statistical analysis.	en
