An exponential failure distribution requires a single argument: the Expected Lifetime. The Expected Lifetime has dimensions An output attribute for an element that defines the dimensionality (in terms of Length, Time and other fundamental dimensions) of the output. of time, and represents the mean lifetime of a container. The curve below shows an exponential distribution that has been delayed by 10 years:
Note: The Expected Lifetime should not be specified as a function of time. If it is, only the initial value will be used.
