[Math] Low-discrepancy sequences

2021-05-30 Thread Gilles Sadowski 
Hello.

Halton and Sobol sequences have been implemented in the "random"
package.  From Wikipedia[1]:
---CUT---
Low-discrepancy sequences are also called quasirandom sequences,
due to their common use as a replacement of uniformly distributed
random numbers. The "quasi" modifier is used to denote more clearly
that the values of a low-discrepancy sequence are neither random nor
pseudorandom.
---CUT---

TL;DR;
I propose to create an interface "LowDiscrepancySequence" to properly
represents the concept (as opposed to "RandomVectorGenerator").

Regards,
Gilles

Signatures are good on everything. Spot checks on basic release stuff
are all good (license, notice, rat check etc.). Built and tested fine
on the following (Java 11, 15, 16):

[Math][Request for review] MATH-1592

2021-05-30 Thread Samy Badjoudj 

Hi,

As part of modularization coming,

https://issues.apache.org/jira/browse/MATH-1592

https://github.com/apache/commons-math/pull/186

The idea there, is that TransformerMap in descriptive statistics, will 
not be part of the api anymore for a clear separation of concerns.

Caller will perform transformations on its side if needed.

Thanks

Kind regards

Hi,

As part of modularization coming,

https://issues.apache.org/jira/browse/MATH-1468

https://github.com/apache/commons-math/pull/185

Decimal64 and Decimal64Field should not be part of the public API, and 
go along with the tests they are us in.


Thanks

Kind regards

Re: [Math] Setup SonarCloud

I created a new token and re-ran the job. It has the same error. So I think
that the copy from the Geometry set-up did copy the authorisation token.

I think that the project must be created in Sonarcloud. In the Jenkins
build configuration, Maven is run with the property:

-Dsonar.projectKey=commons-math

So the commons-math project should exist under the Apache Software
Foundation organisation (which is where my login authorisation token can
send analysis reports). There are 2 projects already in Sonar for
commons-math under private individuals. I assume that we can create an
official one under Apache.

I do not have permissions to create a new analysis project (when I try to
create one under the Apache organisation). So this is a job for INFRA.
Ticket created here:

https://issues.apache.org/jira/browse/INFRA-21932
