Returns the unnormalized value of the measure
Returns the unnormalized value of the measure
Returns a Multinomial distribution over the iterator
Overridden by filter/map/flatmap for monadic invocations.
Overridden by filter/map/flatmap for monadic invocations. Basically, rejeciton samplers will return None here
Converts a random sampler of one type to a random sampler of another type.
Converts a random sampler of one type to a random sampler of another type. Examples: randInt(10).flatMap(x => randInt(3 * x.asInstanceOf[Int]) gives a Rand[Int] in the range [0,30] Equivalently, for(x <- randInt(10); y <- randInt(30 *x)) yield y
the transform to apply to the sampled value.
Samples one element and qpplies the provided function to it.
Samples one element and qpplies the provided function to it. Despite the name, the function is applied once. Sample usage:
for(x <- Rand.uniform) { println(x) }
the function to be applied
Returns the log unnormalized value of the measure
Returns the log unnormalized value of the measure
Returns logNormalized probabilities.
Returns logNormalized probabilities. Use this if you're worried about underflow
Converts a random sampler of one type to a random sampler of another type.
Converts a random sampler of one type to a random sampler of another type. Examples: uniform.map(_*2) gives a Rand[Double] in the range [0,2] Equivalently, for(x <- uniform) yield 2*x
the transform to apply to the sampled value.
Returns the probability density function at that point.
Returns the probability density function at that point.
Gets n samples from the distribution.
Gets n samples from the distribution.
Gets one sample from the distribution.
Gets one sample from the distribution. Equivalent to get()
An infinitely long iterator that samples repeatedly from the Rand
An infinitely long iterator that samples repeatedly from the Rand
an iterator that repeatedly samples
Returns unnormalized probabilities for a Multinomial distribution.
Returns the log pdf function of the Dirichlet up to a constant evaluated at m
Returns the log pdf function of the Dirichlet up to a constant evaluated at m
Returns the probability density function up to a constant at that point.
Returns the probability density function up to a constant at that point.
Represents a Dirichlet distribution, the conjugate prior to the multinomial.
