Class RealUniform

java.lang.Object
org.flag4j.rng.distributions.Distribution<Double,Random>
org.flag4j.rng.distributions.RealUniform
public class RealUniform extends Distribution<Double,Random>

A 1D real uniform distribution \(\mathcal{U}(a, b)\).

The PDF of the uniform distribution \(\mathcal{U}(a, b)\) over the half open interval \( \left[a, b\right) \) where \( a < b \) is given by: \[ f(x) = \begin{cases} \frac{1}{b - a} & \text{for } x \in [a, b), \\ 0 & \text{otherwise}. \end{cases} \]
