Weibull Distribution (Definition, Properties, Plot, Reliability

WebThe exponential distribution is a simple distribution with only one parameter and is commonly used to model reliability data. The exponential distribution is actually a special case of the Weibull distribution with ß = 1. The exponential distribution provides a good model for the phase of a product or item's life when it is just as likely to ... WebThis is the familiar differential equation for exponential decay. The general solution is R ( x) = R ( 0) e − λ x. We were told that R ( 0) = 1. It follows that R ( x) = e − λ x. So the cumulative distribution function F X ( x) of the random variable X is 1 − e − λ x (for x > 0 ). Differentiate with respect to x.
