- lower_bound0Distribution lower bound
Default:0
C++ Type:double
Description:Distribution lower bound
- upper_bound1Distribution upper bound
Default:1
C++ Type:double
Description:Distribution upper bound
Uniform
Continuous uniform distribution.
Description
The uniform distribution is a probability distribution that has constant probability. This is a continuous uniform distribution with the probability density function:
if , then !equation f(x) = 1/(b - a)
if or , then !equation f(x) = 0
where and are the lower bound and upper bound for the uniform distribution, respectively.
