kde1d vs RandomWalker: at a glance
What is kde1d?
A univariate density estimator that added zero-inflated data and reopened its C++ API to do it.
kde1d estimates univariate densities with local polynomial kernel methods, handling bounded, discrete and now zero-inflated variables through a single type argument, with the numerical work in a header-only C++ library usable outside R. Version 1.1.0 added the zero-inflated discrete-continuous mixture case and shipped a new C++ API as an explicit breaking change; 1.1.1 followed in June with auto-generated notes and no description.
What is RandomWalker?
A random-walk generator that outgrew one dimension and renamed its core column to prove it.
RandomWalker generates families of stochastic paths — Brownian motion, geometric Brownian motion, drift walks, discrete walks — as tidy tibbles, with cumulative-statistic augmenters, summarisers and a visualize_walks() plotting layer on top. The development series before 1.0.0 extended generation to two and three dimensions and renamed the step index from x to step_number, which is the shape the package now carries into its stable release.

kde1d
0.0ANALYTICS
A univariate density estimator that added zero-inflated data and reopened its C++ API to do it.
◆ Current state
kde1d estimates univariate densities with local polynomial kernel methods, handling bounded, discrete and now zero-inflated variables through a single type argument, with the numerical work in a header-only C++ library usable outside R. Version 1.1.0 added the zero-inflated discrete-continuous mixture case and shipped a new C++ API as an explicit breaking change; 1.1.1 followed in June with auto-generated notes and no description.
◆ Where it's heading
The package has alternated between performance work and widening the class of data it accepts. The 1.0.0 release was the performance milestone — FFT-based estimation, a better integration algorithm for the p, q and r functions, deterministic jittering replacing randomness, and standalone C++ headers. The 1.1.0 release is the scope milestone, adding a third data type to the two it already handled. Releases come from the same maintainer as svines and cluster on shared dates, so changes in the underlying C++ surface across the vine and density stack tend to ship together.
◆ Prediction
With the C++ API deliberately reworked for standalone use at 1.1.0, further work most plausibly consolidates that interface rather than adding data types. What 1.1.1 actually changed is not readable from its body.
RandomWalker
0.0ANALYTICS
A random-walk generator that outgrew one dimension and renamed its core column to prove it.
◆ Current state
RandomWalker generates families of stochastic paths — Brownian motion, geometric Brownian motion, drift walks, discrete walks — as tidy tibbles, with cumulative-statistic augmenters, summarisers and a visualize_walks() plotting layer on top. The development series before 1.0.0 extended generation to two and three dimensions and renamed the step index from x to step_number, which is the shape the package now carries into its stable release.
◆ Where it's heading
The package built outward in clear stages: generators first, then a set of std_cum_*_augment() transformations over the results, then the dimensional generalisation that forced the column rename. That progression suggests a design settling on walks as a tidy data structure to be transformed and plotted rather than a set of one-off simulators. The 1.0.0 tag itself carries no release notes in this feed — its body is stray YAML front matter — so the milestone's own contents cannot be read here.
◆ Prediction
With dimensions generalised and a 1.0.0 cut, further work most plausibly extends the augmenter and summariser layer to multi-dimensional walks. The empty 1.0.0 body means any specific claim about what the stable release contains would be guesswork.
