Ok, I think I have a bunch of classes available:
(-> what it overrides)
DotProduct
Covariance (storeless)
CorrelationCoefficient (storeless)
abstract LinearRegression (storeless) -> CC
LeastSqaresRegression (storeless) -> linear
MajorAxisRegression (with correct R^2 (minimizing x AND y direction,
which is done wrong so often, storeless) -> Linear
ReducedMajorAxisRegression (see MA) -> MA
Hypotenuse
EigenValueDecomposition (JAMA derived)
SingularValueDecomposition (JAMA derived)
CholeskyDecomposition (JAMA derived)
Distances (Euclidean and Mahalanobis matrix stuff etc)
SpecialMatrices (SSCP, COVAR, CORREL, etc)
MatrixCorrelation
Geometrics (basic tools)
ProcrustesAnalysis (2 matrix) -> Geo
GeneralizedProcrustesAnalysis (n matrix) -> PA
PCA (basic!)
MVE (minimum volume ellipsoid: multivariate outlier detection)
HeapSort (next to slower sort routines)
Is there interest? Most of them are not directly pluggable into
commons.math because I use a derived version of the matrix class (no
interface as a basis, and MatrixUtils integrated). Some is very basic,
other stuff is advanced.
Cheers,
Kim
