public class R1UniformDistribution
extends R1Distribution

R1UniformDistribution implements the Univariate R¹ Uniform Distribution. It implements the Incremental, the Cumulative, and the Inverse Cumulative Distribution Densities. It provides the following Functionality:

• Construct a Standard (0, 1) R¹ Univariate Uniform Distribution
• R1UniformDistribution Constructor
• Retrieve the Left Support
• Retrieve the Right Support
• Indicate if the specified x Value stays inside the Support
• Lay out the Support of the PDF Range
• Compute the cumulative under the distribution to the given value
• Compute the Incremental under the Distribution between the 2 variates
• Compute the inverse cumulative under the distribution corresponding to the given value
• Compute the Density under the Distribution at the given Variate
• Retrieve the Mean of the Distribution
• Retrieve the Variance of the Distribution
• Generate a Random Variable corresponding to the Distribution
