Swift framework for random numbers & distributions.

RandKit

Random number generation for Swift.

##Included Features:

• Distributions
  • Uniform
  • Normal
  • Bernoulli
  • Binomial
  • Exponential
  • Geometric
  • Poisson
  • Weibull
  • Feel free to contribute!
• Generators
• Probabilities

##Usage:

/// Uniform Randomness
let randomZeroToOneTopOpen = random() // [0, 1)
let randomZeroToOneOpen = random(exclusiveMin: 0, exclusiveMax: 1) // (0, 1)
let randomZeroToOneBottomOpen = random(exclusiveMin: 0, inclusiveMax: 1) // (0, 1]
let randomZeroToOneClosed: Double = random(0...1)

/// Probability
let coinFlip: Bool = random(probability: 0.5)

/// Generators
let uniformDistribution = UniformDistribution(range: -1...1)
let uniformGenerator = RandomGenerator(distribution: uniformDistribution)

/// Sampling
let samplingGenerator = SamplingGenerator(elements: ["red", "green", "blue"], uniformDistribution)
let image = samplingGenerator.sample(128, withReplacement: true)
