{{template:ALTABOOK|3}}
In this chapter, we will briefly present three lifetime distributions commonly used in accelerated life test analysis: the exponential, the Weibull and the lognormal distributions. Note that although all forms are mentioned below, ALTA uses the 1-parameter form of the exponential distribution and the 2-parameter form of the Weibull distribution.

Readers who are interested in a more rigorous overview of these distributions (or for information about other life distributions) can refer to the [https://help.reliasoft.com/reference/life_data_analysis Life data analysis reference]. For information about the parameter estimation methods, see [[Appendix_B:_Parameter_Estimation|Appendix B]].<br>
