What is PowerTOST?

A bioequivalence sample-size workhorse whose news is which regulator it now covers

PowerTOST computes power and sample size for bioequivalence and its changelog reads as a record of regulatory divergence more than statistical development. Version 1.5-3 added the Gulf Co-operation Council as a regulator setting; 1.5-4 and 1.5-6 stripped 'FDA' out of the narrow-therapeutic-index function names once China's CDE began requiring the same evaluation. The most recent release, 1.5-7, is a single fix to how nvec() splits a total sample size across sequences.

What is vcmeta?

A meta-analysis toolkit still renaming its own API as it adds effect sizes.

vcmeta provides confidence-interval methods for meta-analysis across correlations, proportions, odds ratios, standardized mean differences and reliability, plus replication-study counterparts to most of them. Each release both widens the function inventory and reshuffles it. The most recent one adds agreement and generalised log-average functions while deleting one function and renaming six others.

◆ Current state

PowerTOST computes power and sample size for bioequivalence and its changelog reads as a record of regulatory divergence more than statistical development. Version 1.5-3 added the Gulf Co-operation Council as a regulator setting; 1.5-4 and 1.5-6 stripped 'FDA' out of the narrow-therapeutic-index function names once China's CDE began requiring the same evaluation. The most recent release, 1.5-7, is a single fix to how nvec() splits a total sample size across sequences.

◆ Where it's heading

The package is in long maintenance with a widening regulatory surface: the statistical methods are settled, and releases arrive when an agency publishes a framework that can be expressed as a settings variant of an existing method. Function naming has been deliberately decoupled from any single agency, with the deprecated FDA-suffixed aliases carried for years before removal. Cadence has slowed to roughly one release every eighteen months.

◆ Prediction

The next release is most likely another regulator setting or a small fix; on the deprecation notice already given, the power.NTIDFDA()-style aliases are the obvious removal candidate.

A meta-analysis toolkit still renaming its own API as it adds effect sizes.

◆ Current state

vcmeta provides confidence-interval methods for meta-analysis across correlations, proportions, odds ratios, standardized mean differences and reliability, plus replication-study counterparts to most of them. Each release both widens the function inventory and reshuffles it. The most recent one adds agreement and generalised log-average functions while deleting one function and renaming six others.

◆ Where it's heading

The package is converging on a naming scheme, with odds becoming oddsratio and ratio.prop2 becoming propratio2, and it is willing to break calling code to get there. Two of the last three releases carry a self-declared breaking parameter change, both cases where an assumption that used to be baked in became something the user must supply. Growth in the function set is steady rather than directional.

◆ Prediction

Expect the renaming pass to continue into the remaining inconsistent names, alongside more replication-study counterparts to existing estimators.
