kdecopula 0.9.2 (2018-04-09)

NEW FEATURES

• faster computations for method = "bern" due to removal of the quadratic programming step for rescaling to uniform margins.

kdecopula 0.9.1 (2017-10-06)

BUG FIXES

• fix bug in interpolation near boundaries (interpolated in wrong cell, see #2, #3).

kdecopula 0.9.0 (2017-05-16)

NEW FEATURES

• user visible functions for bandwidth selection (bw_xxx()) with documentation.

• predict(), fitted(), and simulate() generics.

• make TLL2nn the default method.

• new function dep_measures() for calculating dependence measures.

kdecopula 0.8.1 (2017-04-11)

NEW FEATURES

• stabilized bandwidth matrix transformation.

• faster builds (removed unnecessarily included headers).

• updated documentation.

kdecopula 0.8.0 (2016-12-25)

NEW FEATURES

• Improved bandwidth selection heuristic for methods TLL1/TLL2.

• The Bernstein copula density estimator is documented and comes with an automated smoothing parameter selection routine.

• All bandwidth selection methods now have a manual page (see ?kdecop for links).

• Updated vignette.

BUG FIXES

• fixed inconsistencies in bandwidth specification. The interpretation of the bandwidth matrix is now the same for TLL and T methods.

kdecopula 0.7.0 (2016-11-26)

DEPENDS

• Added quadprog to imports.

NEW FEATURES

• Methods TLL1 and TLL2 now use fixed bandwidths; nearest neighbor methods are implemented as TLL1nn and TLL2n.

• Improved bandwidth selection for methods TLL1nn and TLL2nn.

• Improved memory allocation.

• Hidden (and undocumented) method bern for the Bernstein copula density.

BUG FIXES

• Bandwidth selection for methods TTxx are now safe even when correlation is high and sample size small.

kdecopula 0.6.0 (2016-05-14)

DEPENDS

• Package no longer imports packages cubature and VineCopula.

BUG FIXES

• improved algorithms for numerical inversion

NEW FEATURES

• new function hkdecop to evaluate conditional distributions ("h-functions").

• extended plotting functionality (exponential margins).

• faster calculations of bandwidths for methods "MR" and "beta" due to precalculated integral values.

OTHER

• updated vignette.

kdecopula 0.5.0 (2016-02-16)

BUG FIXES

• fix scaling for method = "MR" when not renormalized.

NEW FEATURES

• package now has a vignette.

BUG FIXES

• rkdecop now properly working with quasi-random numbers.

• improved efficiency of C++ code.

kdecopula 0.4.0 (2015-10-22)

NEW FEATURES
