What is distributions3?

distributions3 0.3.0 adds sample-based distributions and likelihood derivatives

An R package giving probability distributions a consistent object interface - d/p/q/r functions, moments, and prodist() methods that pull a fitted distribution out of a regression object. Version 0.3.0 is the first substantive release under Achim Zeileis's maintenance, and it widens what a distribution is allowed to be: Empirical() represents a distribution by a random sample rather than by parameters, and numerical fallbacks now fill in cdf(), pdf(), quantile(), random() and the moments for any object that implements only some of them. New score() and hessian() generics compute first and second derivatives of the log-likelihood with respect to the parameters, analytically for a few distributions and numerically for the rest.

What is sass?

Nine releases of compiler warnings and CRAN checks — the Sass binding is in pure upkeep.

sass compiles Sass to CSS for R, and its recent history is almost entirely about staying installable. The last ten releases are dominated by compilation warnings on new toolchains — Apple Clang 15, gcc-12, Windows — plus R CMD check fixes for r-devel and one LibSass version bump. The only user-visible changes in the set are the switch to woff2 font files in font_google(local = TRUE) and clearer output when Google fonts are downloaded.

distributions3 vs sass: editorial side-by-side

D6.3

distributions3 0.3.0 adds sample-based distributions and likelihood derivatives

◆ Current state

An R package giving probability distributions a consistent object interface - d/p/q/r functions, moments, and prodist() methods that pull a fitted distribution out of a regression object. Version 0.3.0 is the first substantive release under Achim Zeileis's maintenance, and it widens what a distribution is allowed to be: Empirical() represents a distribution by a random sample rather than by parameters, and numerical fallbacks now fill in cdf(), pdf(), quantile(), random() and the moments for any object that implements only some of them. New score() and hessian() generics compute first and second derivatives of the log-likelihood with respect to the parameters, analytically for a few distributions and numerically for the rest.

◆ Where it's heading

Growth used to arrive as new distribution families contributed from outside - the extreme-value set, Erlang, later the Poisson binomial. This release changes the axis: alongside two new distributions it adds an inference layer (score, hessian) and a forecast-evaluation one (crps() methods against scoringRules), which are capabilities about distributions rather than more of them. Dependency weight is being cut at the same time, with ggplot2 demoted to Suggests and glue replaced by base R sprintf().

◆ Prediction

With numeric fallbacks and the derivative generics in place, expect analytic score() and hessian() methods to be filled in across more of the distribution catalogue. The constructor-default change is the likeliest source of follow-up fixes, since calls like Poisson() now return a length-zero distribution where they previously errored.

Nine releases of compiler warnings and CRAN checks — the Sass binding is in pure upkeep.

◆ Current state

sass compiles Sass to CSS for R, and its recent history is almost entirely about staying installable. The last ten releases are dominated by compilation warnings on new toolchains — Apple Clang 15, gcc-12, Windows — plus R CMD check fixes for r-devel and one LibSass version bump. The only user-visible changes in the set are the switch to woff2 font files in font_google(local = TRUE) and clearer output when Google fonts are downloaded.

◆ Where it's heading

This is a stable binding to a C++ library that is itself no longer moving, so the package's work is defined by the compilers and CRAN policies around it rather than by Sass features. Nothing in these entries suggests active development; the maintenance is competent and prompt, but it is maintenance.

◆ Prediction

The next release will most likely be triggered by a new compiler warning class or an R CMD check requirement rather than by anything in the Sass language. The entries give no signal of planned feature work.
