createSample
public double[] createSample(double p1msmt, double s, double t)
Description copied from class:TriangleSampler
Creates the sample given the random variatess
andt
in the interval[0, 1]
ands + t <= 1
. The sum1 - s - t
is provided. The sample can be obtained from the triangle abc using:p = a(1 - s - t) + sb + tc
- Specified by:
createSample
in classTriangleSampler
- Parameters:
p1msmt
- plus 1 minus s minus t (1 - s - t)s
- the first variate st
- the second variate t- Returns:
- the sample
-
withUniformRandomProvider
public TriangleSampler withUniformRandomProvider(UniformRandomProvider rng)
Description copied from class:TriangleSampler

withUniformRandomProvider
in interfaceSharedStateSampler<SharedStateObjectSampler<double[]>>
- Specified by:
withUniformRandomProvider
in classTriangleSampler
- Parameters:
rng
- Generator of uniformly distributed random numbers.- Returns:
- the sampler
