rdevdict::exponential


Name:
rdevdict::exponential - exponential random deviate generator
Description:
Generates exponentially distributed random numbers.  
Negative values of lambda are allowed and generate a distribution
of negative numbers.

For lambda > 0:
p(x) = lambda exp(-lambda*x), for x >= 0
p(x) = 0, for x < 0

For lambda < 0:
p(x) = 0, for x > 0
p(x) = |lambda| exp ( -|lambda| |x| ), for x <= 0

Parameters:
 
lambda - rate parameter (default: 1.0)
