What is discretetests?
Four years of releases land in four minutes as the changelog gets backfilled to GitHub
DiscreteTests computes exact p-values and their full support for discrete statistical tests, returning results as a class that carries the observations, the test statistic and the null distribution. All four visible releases were tagged within four minutes of each other on a single day in May 2026, in reverse order — 0.4.1 carries the earliest timestamp and 0.4.0 the latest — so this is a historical changelog being pushed to GitHub at once, not four days of work.
What is portfoliobacktest?
Four dormant years end with a test fix, not a feature
portfolioBacktest runs portfolio strategies across multiple datasets and resampled windows, producing performance tables, leaderboards and charts. After a run of substantive releases through 2021 and early 2022 it went quiet for four years. The May 2026 release does one thing: fix unit tests against a breaking change in PerformanceAnalytics::Return.portfolio(), which now returns results for the full input series rather than only from the first weight date.

◆ Current state
DiscreteTests computes exact p-values and their full support for discrete statistical tests, returning results as a class that carries the observations, the test statistic and the null distribution. All four visible releases were tagged within four minutes of each other on a single day in May 2026, in reverse order — 0.4.1 carries the earliest timestamp and 0.4.0 the latest — so this is a historical changelog being pushed to GitHub at once, not four days of work.
◆ Where it's heading
Read by version rather than by timestamp, the package grew from binomial, Fisher, McNemar and Poisson tests into rank-based and resampling territory: Wilcoxon signed rank and rank sum, Mann-Whitney U, a conditional homogeneity test, then sign tests and a general permutation test with several built-in statistics. Alongside that the result class was extended to hold ragged observation lists and computational detail, the print output was rewritten on cli, and the old dot-separated function names were made defunct.
◆ Prediction
The permutation test with pluggable statistics is the most open-ended addition here, and adding further built-in statistics to it is the cheapest way to extend the package from where it now stands.

The May 2026 release does one thing: fix unit tests against a breaking change in PerformanceAnalytics::Return.portfolio(), which now returns results for the full input series rather than only from the first weight date.
◆ Where it's heading
The development work is behind it. The 2019 to 2022 releases built the substance — parallel execution, resampling that works beyond stock data and beyond daily bars, transaction-cost-aware designs through w_current, and a switch from compounded to uncompounded returns in the Sharpe and annualized return calculations. Since then the package has moved only when a dependency forced it, and even then only far enough to keep the tests green.
◆ Prediction
Nothing in the entries suggests planned work; the next release is most likely triggered by another dependency change, on the same four-year-gap pattern.

Frequently asked questions
What is the difference between discretetests and portfoliobacktest?
Both compete on the same themes — r-package — within Infra & APIs. discretetests and portfoliobacktest 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 discretetests better than portfoliobacktest?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. discretetests and portfoliobacktest are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
