value) if the result is too large to store as an integer.
Fixes 35431.
Thanks to Jörg Weimar.
| psteitz |
|
Added factories for TTest, ChiSquareTest and TestUtils class with
static methods to create instances and execute tests.
Fixes 32663.
Thanks to Mary Ellen Foster.

|
Eliminated repeated endpoint function evalutations in BrentSolver, SecantSolver.
Fixes 35042.
Thanks to Paul Field.
| psteitz |
|
Added setSubMatrix methods to RealMatrixImpl, BigMatrixImpl. To
Preserve backward compatibility with versio
n 1.0, these methods were
not added to the RealMatrix, BigMatrix interfaces.
Fixes 35007.
Thanks to Rodrigo di Lorenzo Lopes.
| psteitz |
|
Added createXIdentityMatrix methods to MatrixUtils and deprecated
getIdentity methods in RealMatrixImpl, BigMatrixImpl.
Modified RealMatrixImpl, BigMatrixImpl constructors to throw
IllegalArgumentExceptions instead of ArrayIndexOutOfBounds when
dimension arguments are not positive.
| psteitz |
|
Made PRNG pluggable for classes in the random package. Added
RandomGenerator interface extracted from java.util.random and abstract
implementation, AbstractRandomGenerator providing default
implementations of methods based on nextDouble(). Added a constructor
taking a RandomGenerator as an argument to RandomDataImpl. Changed
ValueServer to use a RandomData in its constructor. Changes to
1.0 classes should be backward compatible (including serialization).
| psteitz |
|
Added utility methods for overflow-checked integer arithmetic and
improved gcd method in MathUtils.
Thanks to C. Scott Ananian.
| psteitz |
|

incorrectly using heteroscedastic t statistic. Also improved
sensitivity of test cases.
Fixes 34677.
Thanks to Gilles Gaillard.
| psteitz |
|
