kdecopula 0.9.0

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

NEW FEATURES

  • stabilized bandwidth matrix transformation.

  • faster builds (removed unnecessarily included headers).

  • updated documentation.

kdecopula 0.8.0

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

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

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

BUG FIXES

  • fix scaling for method = “MR” when not renormalized.

NEW FEATURES

  • package now has a vignette.

kdecopula 0.4.1

BUG FIXES

  • rkdecop now properly working with quasi-random numbers.

  • improved efficiency of C++ code.

kdecopula 0.4.0

NEW FEATURES

  • New estimation method: tapered transformation estimator (methods “TTPI” and “TTCV”). Thanks to Kuangyu Wen for sharing code!

kdecopula 0.3.0

NEW FEATURES
