) |
Constructs an exponential random variable with specified mean and upper limit.
Since exponential distributions can theoretically return unbounded values, it is sometimes useful to specify a fixed upper limit. Note however when the upper limit is specified, the true mean of the distribution is slightly smaller than the mean value specified: .
m | Mean value of the random variable |
b | Upper bound on returned values |
