What is JointFPM?

Recurrent-event modelling settles, with mean_no() promoted to stable.

JointFPM fits joint flexible parametric models for a recurrent event process alongside a competing terminal event, and predicts the mean number of events. The visible history runs from bug fixes on the earliest CRAN releases through standardization, integration options and a summary method, ending with mean_no() declared stable. Several changes arrived through outside pull requests.

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.

Recurrent-event modelling settles, with mean_no() promoted to stable.

◆ Current state

JointFPM fits joint flexible parametric models for a recurrent event process alongside a competing terminal event, and predicts the mean number of events. The visible history runs from bug fixes on the earliest CRAN releases through standardization, integration options and a summary method, ending with mean_no() declared stable. Several changes arrived through outside pull requests.

◆ Where it's heading

The arc runs from a working estimator toward a usable one: input validation and error messages first, then control over the numerical integration, then a summary method and pass-through arguments to the underlying rstpm2 fit. The latest release adds no code so much as a stability commitment to a function users were already calling.

◆ Prediction

With mean_no() stable, the next work most likely targets the prediction and standardization paths rather than the model fit itself.

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

◆ 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.

Frequently asked questions

What is the difference between JointFPM and PowerTOST?

They serve adjacent needs but don't currently overlap on shipped themes. JointFPM and PowerTOST are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.

Is JointFPM better than PowerTOST?

Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. JointFPM and PowerTOST are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
