Alex Herbert created STATISTICS-33:
--------------------------------------
Summary: Remove the utility function to create an array of samples
from a Sampler
Key: STATISTICS-33
URL: https://issues.apache.org/jira/browse/STATISTICS-33
Project: Apache Commons Statistics
Issue Type: Improvement
Components: distribution
Affects Versions: 1.0
Reporter: Alex Herbert
The following utility methods can be removed:
{code:java}
abstract class AbstractDiscreteDistribution {
public static int[] sample(int n,
DiscreteDistribution.Sampler sampler)
}
abstract class AbstractContinuousDistribution {
public static double[] sample(int n,
ContinuousDistribution.Sampler sampler)
}
{code}
They exists as utility methods in a package-private abstract class (thus the
public modifier is confusing). I suggest moving them to TestUtils. They can be
replicated in code by using a stream:
{code:java}
ContinuousDistribution d = ...;
UniformRandomProvider rng = ...;
int n = 1000;
double[] samples = DoubleStream.stream(d.createSampler(rng)::sample)
.limit(n)
.toArray();
{code}
