WebApr 23, 2024 · Distribution Functions. The basic Weibull distribution with shape parameter k ∈ (0, ∞) is a continuous distribution on [0, ∞) with distribution function G given by G(t) = 1 − exp( − tk), t ∈ [0, ∞) The special case k = 1 gives the standard Weibull distribution. The Weibull distribution is named for Waloddi Weibull. WebThe exponential distribution (also called the negative exponential distribution) is a probability distribution that describes time between events in a Poisson process. There is a strong relationship between the Poisson …

In probability theory and statistics, the exponential distribution or negative exponential distribution is the probability distribution of the time between events in a Poisson point process, i.e., a process in which events occur continuously and independently at a constant average rate.
