Kevin Milner created STATISTICS-93:
--------------------------------------
Summary: TruncatedNormalDistribution: add methods to expose
construction parameters
Key: STATISTICS-93
URL: https://issues.apache.org/jira/browse/STATISTICS-93
Project: Commons Statistics
Issue Type: Improvement
Components: distribution
Affects Versions: 1.0
Reporter: Kevin Milner
TruncatedNormalDistribution doesn't expose the parameters used to construct it.
As far as I can tell, it's the only distribution that doesn't currently expose
all of the necessary information to reconstruct it.
My use case is that I'm interested in creating a Gson TypeAdapter in my
projects that can [de]serialize these distributions, but the current
TruncatedNormalDistribution cannot be serialized without an extra abstraction
layer or using reflection.
I propose adding:
{code:java}
public double getParentMean();
public double getParentStandardDeviation();{code}
and/or adding:
{code:java}
public NormalDistribution getParentDistribution(); {code}
This is in line with other distributions that provide getters for parameters
not in the ContinuousDistribution interface, e.g.,
NormalDistribution.getStandardDeviation() or LogNormalDistribution.getMu().
I'm happy to make a PR for this, but wanted to run it by you first. Also feel
free to make the change yourself if you agree and would prefer to bypass the
external PR steps.
Thanks for your consideration!
