NEWS file for the MBBEFDLite package

Developmental Note: Version 0.0.0+

• So long as the package remains in its experimental development state—noted by a 0 major version—the API may change without incrementing the major version. Please read these development notes carefully. Breaking changes will be prefaced by “Breaking:”.

Version 0.1.0 (2026-01-07)

Added

• Breaking: The mommb algorithm now calculates E[x^2] as (E[x]) ^ 2 + Var[x] instead of directly as E[x ^ 2]. Using the unbiased estimator allows for a slightly larger initial estimate. Given that the algorithm fails earlier, this allows for a slighltly larger legal starting location. The results are functionally identical, but not always equal within machine tolerances, so the change is breaking.

• Breaking: The mommb algorithm now allows for passing a couplet consisting of the first two raw moments through x when new parameter m is set to TRUE. When m is FALSE, the default, x is treated as a vector of observations regardless of its length. This is breaking as the positions of the parameters has now changed.

• A new parameter trace has been added that when TRUE will cause mommb to print the values of g and b at each iteration i.

Changed

• Breaking: The mommb algorithm now fails immediately when the integration would imply a negative p, instead of restarting with a different g. Experimentation indicates that the restart never helped.

• Made tol in mommb a bit less intrusive by passing NULL and then checking for it.

• Use R API Memzero instead of memset.

• Changed Github-related files and workflows.

• Updated unit tests.

Version 0.0.5 (2025-01-31)

Changed

• Replaced \() shorthand with full function call in mommb to remove dependency on R \ge 4.1.0.

• Updated package metadata test.

Changed

• Use log1p instead of log 1.0 + ... where appropriate.

Version 0.0.4 (2024-07-24)

Fixed

• Corrected documentation in ecmb.

• Fixed one unit test.

Changed

• Use log1p instead of log 1.0 + ... where appropriate.

Version 0.0.3 (2024-06-20)

Changed

• Adjust R code for mommb to be more efficient.

• Update documentation.

• Use native CRAN DOI.

• Expand package metadata tests.

Version 0.0.2 (2024-05-16)

Fixed

• Corrected package link in ‘CITATION’.

• Removed extra parentheses in description of g in docs.

Added

• Expanded documentation of ecmb.

• Added DOI.

Version 0.0.1 (2024-05-14)

• Initial release.
