kde1d 1.1.0

NEW FEATURES

• Added functionality for estimating zero-inflated discrete-continuous mixtures.

• New kde1d(..., type = "...") argument to specify the data type. Options are
  {c, cont, continuous} for continuous variables, {d, disc, discrete} for
  discrete integer variables, or {zi, zinfl, zero-inflated} for zero-inflated
  variables.

BREAKING CHANGE

• New C++ API, making it easier to use stand-alone.

kde1d 1.0.4

BUG FIXES

• avoid bit-wise operations on Boolean variables.

kde1d 1.0.3

BUG FIXES

• fix invisible output in dkde1d().

kde1d 1.0.2

BUG FIXES

• Prevent false positive on valgrind.

kde1d 1.0.1

DEPENDENCIES

• Removed dependence on qrng (#46).

BUG FIXES

• Fixed undefined behavior with potential to cause memory issues (#46).

• Prevent rare bw_ == NaN cases (#46).

• Fixed compiler warnings due to unused or uninitialized variables (#46).

kde1d 1.0.0

NEW FEATURES

• optimal plug-in bandwidth selection for all polynomial degrees (#38).

• avoid randomness through simplified, deterministic jittering, see
  equi_jitter() (#40).

• removed dependency cctools.

• headers in inst/include can be used as standalone C++ library with
  convenience wrappers for R (#41).

• (several times) faster pkde1d(), qkde1d(), and rkde1d() due to
  a more clever algorithm for numerical integration (#42).

• faster kde1d() thanks to the Fast Fourier Transform (#43).

BUG FIXES

• improvements to numerical stability, inter- and extrapolation (#32, #35,
  #37).

kde1d 0.4.0

NEW FEATURE

• allow weights for observations via kde1d(..., weights = ) (#29).

BUG FIX

• stabilized bandwidth selection in presence of ties and outliers.

• keep debug symbols on Linux systems (following a request by Prof. Ripley).

kde1d 0.2.1

BUG FIXES

• fix bug in computation of effective degrees of freedom when deg = 2.

kde1d 0.2.0

NEW FEATURES

• improved stability of density estimates near a boundary (#21).

BUG FIXES

• consistent behavior when dkde1d() and pkde1d() are called with
  non-ordered input although data are discrete (#19).

• fixed bug in computation of kernel density estimates (#20).

• adapt minimum bw allowed for discrete data to truncated Gaussian kernel
  (#20).

kde1d 0.1.2

NEW FEATURES

• Faster interpolation using binary search to find cells (#17).

BUG FIXES

• Fixed heap buffer overflows in interpolation routines (#15, #16).

• Fixed bounds of cdf for fit discrete data when long doubles are not
  supported (#16).
