dubicube vs medsim: at a glance
What is dubicube?
dubicube grew from a bootstrap helper into the uncertainty layer other B-Cubed packages call.
dubicube supplies bootstrapping and confidence-interval machinery for biodiversity data cubes in the B-Cubed project. The 0.10–0.12 series added the things a library needs to be depended on rather than copied: automatic detection of group-specific versus whole-cube bootstrapping, an optional boot backend, and then a second capability area in 0.12.0 with data quality diagnostics and cube filtering. The sibling indicator package b3gbi now delegates its confidence intervals here.
What is medsim?
medsim is turning simulation runs into auditable artifacts, not just fast ones.
medsim is a young Monte Carlo harness for mediation-analysis simulation studies, first tagged in May 2026 and already at 0.5.1. The last two releases moved the package's center of gravity from running simulations to proving a run is trustworthy: chunk provenance headers, a single-SHA assertion across chunks, and a pilot-subset positive control. The statistical work sits in the missing-data line added in 0.2.0 — Fleishman non-normal generators, rate-calibrated MCAR/MAR/MNAR amputation, and a validated D4-stacked MBCO estimator.

dubicube
0.0ANALYTICS
dubicube grew from a bootstrap helper into the uncertainty layer other B-Cubed packages call.
◆ Current state
dubicube supplies bootstrapping and confidence-interval machinery for biodiversity data cubes in the B-Cubed project. The 0.10–0.12 series added the things a library needs to be depended on rather than copied: automatic detection of group-specific versus whole-cube bootstrapping, an optional boot backend, and then a second capability area in 0.12.0 with data quality diagnostics and cube filtering. The sibling indicator package b3gbi now delegates its confidence intervals here.
◆ Where it's heading
Release notes are terse — usually one line and an issue number — but the direction is legible in what gets automated. Decisions the caller used to make explicitly are being inferred: resampling scope in 0.10.0, the no-bias option in 0.11.0, and process_cube_args threaded through filter_cube() so the filtering path matches cube processing. The diagnostics work in 0.12.x is the newer line, and 0.12.2's rename of the heatmap option to rule suggests that surface is still settling.
◆ Prediction
The diagnostics and filtering additions have needed a follow-up fix in each of the two releases since they landed, so the next release is most likely more consolidation there rather than a new capability area.
medsim
6.3ANALYTICS
medsim is turning simulation runs into auditable artifacts, not just fast ones.
◆ Current state
medsim is a young Monte Carlo harness for mediation-analysis simulation studies, first tagged in May 2026 and already at 0.5.1. The last two releases moved the package's center of gravity from running simulations to proving a run is trustworthy: chunk provenance headers, a single-SHA assertion across chunks, and a pilot-subset positive control. The statistical work sits in the missing-data line added in 0.2.0 — Fleishman non-normal generators, rate-calibrated MCAR/MAR/MNAR amputation, and a validated D4-stacked MBCO estimator.
◆ Where it's heading
The arc is toward defensible HPC runs: each 0.5.x gate closes a way a cluster job could silently produce wrong output, and 0.5.1 extends the same suspicion to the estimator itself by exposing the branch disagreement the standard ARIV averages away. Releases are cadenced against discovered defects rather than a roadmap — 0.5.0 cites seven findings from a pre-integration review, and 0.5.1 cites an adversarial review of 0.5.0. The audit surface is widening faster than the method surface.
◆ Prediction
The collapse-audit exclusion list has now been patched twice for method-specific diagnostic columns, so the next likely move is a contract letting methods declare their own discrete fields instead of medsim naming them centrally.
