ExponentialValue
RiskAMP Random Distribution Functions
Using this function in Excel:
=ExponentialValue(Beta)
Function arguments:
| Beta | Scale (mean) |
Returns a sample from the exponential distribution. The scale parameter, β, is the mean of the distribution.
The exponential distribution is also commonly parameterized with λ, the rate or inverse scale. β = 1/λ, so if you have the rate parameter call the function with 1/λ.
