There have been numerous bug fixes and -several improvements on performances or robustness. See below -for a full list. - -The minimum version of the Java platform required to compile and use -Apache Commons Math is Java 5. - -Users are encouraged to upgrade to this version as this release not -only includes bug fixes but also deprecates numerous classes and -methods that will be deleted from the next major release (4.0). - - -Caveat: - 1. The implementation of the BOBYQA optimization algorithm is in alpha - state (cf. MATH-621): Many code paths are untested, and we are looking - for volunteers to improve the code readability, robustness and performance - and to extend the unit tests suite. - 2. A few methods in the FastMath class are in fact slower that their - counterpart in either Math or StrictMath (cf. MATH-740 and MATH-901). +This is a maintenance release: It fixes issue MATH-1188. Changes in this version include: -New features: -o MATH-1066: Added Bessel functions of the first kind, based on NetLib implementation. Thanks to Brian Wignall. -o MATH-1180: Method to create a sequence of integers (in "o.a.c.m.util.MathArrays"). -o MATH-1172: New class "SimpleCurveFitter": Boiler-plate code to allow fitting of - a user-defined parametric function. -o MATH-1173: New classes "TricubicInterpolatingFunction" and "TricubicInterpolator" to - replace "TricubicSplineInterpolatingFunction" and "TricubicSplineInterpolator". -o MATH-1166: New classes "BicubicInterpolatingFunction" and "BicubicInterpolator" to - replace "BicubicSplineInterpolatingFunction" and "BicubicSplineInterpolator". -o Boundary attributes in regions now provides the BSP tree nodes that - were used to split the sub-hyperplane forming the boundary part of the facet. -o MATH-1144: Interface to allow parameter validation in "o.a.c.m.fitting.leastsquares": - the point computed by by the optimizer can be modified before evaluation. -o MATH-1154: Changed classes in the inference package that instantiate distributions to - pass null RandomGenerators to avoid initialization overhead for the default - generator. -o MATH-1156: Added all Java 8 StrictMath methods to FastMath, so FastMath remains compatible - with newer Java versions. -o MATH-1139: Added Gumbel, Laplace, Logistic and Nakagami distributions. Thanks to Alexey Volkov. -o MATH-1120: Added several different estimation types and NaN handling strategies for Percentile. Thanks to Venkatesha Murthy. -o MATH-418: Added implementation of PSquare algorithm to estimate percentiles without - storing data in memory (i.e. as StorelessUnivariateStatistic). Thanks to Venkatesha Murthy. Fixed Bugs: -o MATH-1142: Improve performance of kalman gain calculation in "KalmanFilter" by - directly solving a linear system rather than computing the matrix - inverse. Thanks to Arne Schwarz. -o MATH-1181: Fixed integer overflow in KolmogorovSmirnovTest causing 2-sample test - to use exact method when the product of the sample sizes exceeds - Integer.MAX_VALUE, resulting in effectively hung execution. -o MATH-1178: Fixed example in userguide ("stat" section). Thanks to Dmitriy. -o MATH-1175: Fixed inverse cumulative probability of 0 in "LaplaceDistribution". Thanks to Karsten Loesing. -o MATH-1174: Fixed a problem with too thin polygons considered to have infinite size. -o MATH-1162: Fixed a problem with vanishing cut sub-hyperplanes during BSP tree merging. -o MATH-1167: "o.a.c.m.stat.regression.OLSMultipleLinearRegression": Use threshold - when performing "QRDecomposition". Thanks to Neil Ireson. -o MATH-1165: "FuzzyKMeansClusterer" has thrown an exception in case one of the data - points was equal to a cluster center. Thanks to Pashutan Modaresi. -o MATH-1160: Provide access to state derivatives in ContinuousOutputModel. -o MATH-1138: Fixed bicubic spline interpolator, using Akima splines. Thanks to Hank Grabowski. -o MATH-1147: Added statistics missing from toString method in SummaryStatistics. -o MATH-1152: Improved performance of "EnumeratedDistribution#sample()" by caching - the cumulative probabilities and using binary rather than a linear search. Thanks to Andras Sereny. -o MATH-1148: "MonotoneChain" did not take the tolerance factor into account when - sorting the input points. In case of collinear points this could result - in a "ConvergenceException" when computing the hull. Thanks to Guillaume Marceau. -o MATH-1151: Interface "ValueAndJacobianFunction" is a precondition for lazy - evaluation (in "o.a.c.m.fitting.leastsquares"). -o MATH-1145: Fix potential integer overflows in "MannWhitneyUTest" when providing - large sample arrays. Thanks to Anders Conbere. -o MATH-1149: Fixed potential null pointer dereferencing in constructor of - "DummyStepInterpolator(DummyStepInterpolator)". Thanks to M Kim. -o MATH-1136: Fixed BinomialDistribution to deal with degenerate cases correctly. Thanks to Aleksei Dievskii. -o MATH-1135: "MonotoneChain" failed to generate a convex hull if only a minimal hull - shall be created (includeCollinearPoints=false) and collinear hull points - were present in the input. Thanks to Guillaume Marceau. -o MATH-1131: Improve performance of "KolmogorovSmirnovTest#kolmogorovSmirnovTest(...)" for - large samples. Also changed implementation for large n to use Pelz-Good - approximation. Thanks to Schalk W. Cronjé. -o MATH-1134: "BicubicSplineInterpolatingFunction": all fields made final and initialized in - the constructor. Added flag to request initialization, or not, of the internal - data needed for partial derivatives. -o MATH-984: Constrained EmpiricalDistribution sample/getNextValue methods to return - values within the range of the data; correctly linked RandomGenerator to - superclass so that RealDistribution reseedRandomGenerator method works. -o MATH-1129: "Percentile": wrong sorting in the presence of NaN. -o MATH-1127: Fixed overflow in Precision.equals with ulps (both double and float versions). -o MATH-1125: Performance improvements for Student's t-distribution. Thanks to Ajo Fod. -o MATH-1123: Fixed NullPointerException when chopping-off a sub-hyperplane - that is exactly at a region boundary. Thanks to Aurélien Labrosse. -o MATH-1121: "BrentOptimizer": increment base class iteration counter. Thanks to Ajo Fod. +o MATH-1188: Fixed non-Java1.5 code in BesselJ. -Changes: -o Spurious vertices in the middle of otherwise straight edges are now - filtered out when rebuilding polygons boundaries from BSP trees. -o MATH-1128: Added lazy evaluation to "LeastSquaresFactory" (in "o.a.c.m.fitting.leastsquares") - to avoid evaluating the model when the optimization algorithm does not actually - require it.
