Interpret weibull distribution
WebThe hypergeometric distribution is similar to the binomial distribution in that both describe the number of times a particular event occurs in a fixed number of trials. The difference is that binomial distribution trials are independent, whereas hyper-geometric distribution trials change the probability for each subsequent trial and WebMar 21, 2003 · A log-logistic accelerated life model, for example, has an attenuating hazard ratio. With the Weibull distribution, model misspecification is not an issue as it belongs to both families of models. In practice, with a range of easily accessible computing analysis tools, it is worth considering both proportional hazards and accelerated life models.

http://reliabilityofthings.com/how-to-make-a-weibull-analysis-in-5-steps/ WebThe log of the Weibull hazard is a linear function of log time with constant plog + logpand slope p 1. Thus, the hazard is rising if p>1, constant if p= 1, and declining if p<1. The Weibull is also related to the extreme-value distribution: T ˘ W( ;p) i Y = logT= + ˙W; where Whas the extreme value distribution, = log and p= 1=˙.
