This page aims to be a handy reference not only of the work done but
|
|
|
|
|
also of work pending for the next planned release. Users who want new
|
|
|
|
|
features should submit patches to this page in the unclassified section
|
|
|
|
|
of this document. Developers who want to lend a hand can grab tasks from
|
|
|
|
|
this page. Everyone can see the progress which is being made.

in helping out here, what we could really use is a wider selection of

test cases for the core numerical functions and validation against either

other packages (e.g. R for the statistical stuff), verified datasets,

t-test statistic needs to be added and we should probably add the

The RealMatrixImpl class is missing some key method implementations.
|
|
|
|
|
The critical thing is solution of linear systems. We need to implement a
|
|
|
|
|
numerically sound solution algorithm. This will enable inverse() and also
|
|
|
|
|
support general linear regression.

Added double[] |-> double methods in StatUtils to take start indexes and length

|
as parameters and delegate the current "full array" versions to these.
