The legacy module contains most of what was in Commons Math 3. This is code that has not been refactored into modules within the modular Commons Math 4 layout, or undergone a complete rewrite as a new project (see Commons RNG, Numbers, Statistics and Geometry).

Re: math: how to initialize a custom prob. distribution function
thanks. i see this is filed under legacy namespace with the comment Implementations of common discrete and continuous distributions. [Mostly moved to the "Commons Statistics" project (cf. JIRA: MATH-1443).] i then checked https://commons.apache.org/proper/commons-statistics/commons-statistics-distribution/apidocs/allclasses-noframe.html but could not see this class there. should i still use commons-math? and the 4.0-beta1 does not seem to be in maven repository. could i get link to mvn coordinates if its published on maven?

Re: math: how to initialize a custom prob. distribution function
This may be what you require: https://commons.apache.org/proper/commons-math/javadocs/api-4.0-beta1/org/apache/commons/math4/legacy/distribution/EmpiricalDistribution.html You will have to convert your float values to double and then specify the bin size: float[] x = ... int bins = 100; ContinuousDistribution d = EmpiricalDistribution.from(bins, IntStream.range(0, x.length).mapToDouble(i -> x[i]).toArray()); On Fri, 29 Sept 2023 at 17:44, Siddharth Jain wrote: > > I have a vector float[] x containing samples of a random variable.

math: how to initialize a custom prob. distribution function
I have a vector float[] x containing samples of a random variable. I would like to initialize a prob. distribution fn. using these samples and then be able to call methods like https://commons.apache.org/proper/commons-statistics/commons-statistics-distribution/apidocs/org/apache/commons/statistics/distribution/ContinuousDistribution.html I am looking for an API like: var f = ContinuousDistribution.of(x) is this available in commons-math? thanks.

Re: Projects that use org.apache.commons.math3.optim.linear.*;
Hi Jorge, This may be of some help in building a list: https://mvnrepository.com/artifact/org.apache.commons/commons-math3 I think you would need to do some digging to get the fine detail and this would only be that fraction that is mavenised.

Please provide a patch attached to a Jira ticket or a PR for a failing unit
