Parametric Survival Models - Princeton University
data.princeton.eduThe Gompertz distribution is characterized by the fact that the log of the hazard is linear in t, so (t) = expf + tg and is thus closely related to the Weibull distribution where the log of the hazard is linear in logt. In fact, the Gompertz is a log-Weibull distribution. This distribution provides a remarkably close t to adult mortality in
9. The Weibull Distribution
math.bme.huThe Weibull Distribution In this section, we will study a two-parameter family of distributions that has special importance in reliability. The Basic Weibull Distribution 1. Show that the function given below is a probability density function for any k > 0: f(t)=k tk−1 exp(−tk), t > 0

When it is less than one, the hazard function is convex and decreasing. t h(t) Gamma > 1 = 1 < 1 Weibull Distribution: The Weibull distribution can also be viewed as a generalization of the expo-

The goodness-of-fit tests are described in detail for uncensored in the documentation for Distribution Fitting (Uncensored Data) and for censored data in Distribution Fitting (Censored Data.
