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.

CRAN release: 2024-01-26

DEPENDS

  • stop enforcing C++11.

CRAN release: 2022-09-16

BUG FIXES

  • fix cdf and input checks with NAs.

kde1d 1.0.4

CRAN release: 2022-03-16

BUG FIXES

  • avoid bit-wise operations on Boolean variables.

CRAN release: 2020-10-26

BUG FIXES

kde1d 1.0.0

CRAN release: 2019-11-15

DEPENDENCIES

  • removed dependency on cctools.

NEW FEATURES

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