5.1 Survival Function - faculty.washington.edu
The Weibull distribution is a distribution with two parameters, and k, and it is a distribution for positive random variable. Its PDF is p(t) = k( t)k 1 e ( t)k;t 0: When k= 1, it reduces to the exponential distribution. Its CDF and survival function are F(t) = 1 e ( t)k; S(t) = e ( t)k:

Tips and Tricks for Analyzing Non-Normal Data - Quality Mag
www.qualitymag.comFor instance, the Weibull distribution is quite common when modeling time-to-failure data. This versatile distribution can be skewed left, skewed right, or even approximately symmetric. When analyzing data where the risk of failure does not depend on the age of the unit, the exponential distribution may be most suitable. For example,
