kde1d 1.1.1

BUG FIX

• Fix template deduction ambiguity in pre-CXX17 compilers.

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 1.0.7

DEPENDS

• stop enforcing C++11.

kde1d 1.0.5

BUG FIXES

• fix cdf and input checks with NAs.

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

DEPENDENCIES

• removed dependency on cctools.

NEW FEATURES

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

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

• 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 0.2.0

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).

kde1d 0.1.0

• Initial release.
