kdensity 1.2.0 (2026-05-04)

• New closed-form bandwidth selector "HS", based on Hallberg Szabadváry’s beta reference rule (arXiv:2601.19553). It is now the default bandwidth for the bias-corrected beta kernel with a uniform or constant start, with a fallback heuristic when the rule’s moment conditions are not satisfied.
• RHE no longer depends on the EQL package; the Hermite polynomials are evaluated inline (matches the previous numeric output to ~1e-12).
• Trimmed dependencies: EQL removed from Imports; assertthat, testthat, extraDistr, and other build-time helpers no longer required at install time.
• Internal cleanup: the R/ source layout is consolidated into bandwidths.R, kernels.R, starts.R, and helpers.R; no user-visible API changes.

kdensity 1.1.1 (2025-02-18)

• Added support for update of univariateML to version 1.5.
• There are breaking changes in the new version univariateML, but only for this package.
• The new package update is designed to work with univariateML less than 1.5 as well.

kdensity 1.1.0 (2019-01-10)

• Journal of Open Source Software Release.
• Safer kdensity object structure.
• Cleaned up readme and documentation.

kdensity 1.0.1 (2019-07-11)

• Fixed the laplace kernel.
• kdensity: Added error message when the normalization constant fails to be accurate enough and a tolerance parameter to control it.
• Better error messages when data is not in the support of the parametric starts.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
