What is BAS?

A Bayesian model-averaging package spending its 2.0 on memory, not methods.

BAS performs Bayesian variable selection and model averaging for linear and generalized linear models, sampling from a model space too large to enumerate. The visible history splits cleanly: 2023-2024 added sampling machinery — an adaptive independent MCMC sampler with Horvitz-Thompson estimation, hereditary-constraint counting — while 2.0.0 in late 2025 reworked how sampler output is allocated in C. The 2.0.2 patch is a PROTECT fix for rchk warnings.

What is incident.io?

Nexus does the diagnosis; the agent is now reaching into the status page too.

Investigations went generally available earlier this month, with Nexus posting a root-cause hypothesis and its evidence into the incident channel within minutes of declaration. The releases since have been the operational surround: a 24/7 schedule coverage policy that flags gaps before someone is missing from a rotation, more filtering in Insights, escalation reassignment, and now status page updates written by the agent alongside Pingdom uptime metrics and self-serve language settings.

A Bayesian model-averaging package spending its 2.0 on memory, not methods.

◆ Current state

BAS performs Bayesian variable selection and model averaging for linear and generalized linear models, sampling from a model space too large to enumerate. The visible history splits cleanly: 2023-2024 added sampling machinery — an adaptive independent MCMC sampler with Horvitz-Thompson estimation, hereditary-constraint counting — while 2.0.0 in late 2025 reworked how sampler output is allocated in C. The 2.0.2 patch is a PROTECT fix for rchk warnings.

◆ Where it's heading

Memory is the binding constraint and the releases say so directly. The hereditary-constraint counter, the GROW option, and the replacement of over-allocation with resizing all attack the same problem: n.models is a guess, and guessing high wastes memory on problems where few unique models are actually visited. The 2.0.0 work was additionally forced by R tightening its C API against non-API calls like SETLENGTH, a constraint every C-heavy CRAN package has been absorbing. Method development has been quiet since 1.7.x.

◆ Prediction

The 1.7.5 notes call the hereditary-constraint counting a first step and say future updates will cover other constraint types, including polynomials, which remain unhandled. That is the one concrete commitment in this history, though nothing since has returned to it.

Nexus does the diagnosis; the agent is now reaching into the status page too.

◆ Current state

Investigations went generally available earlier this month, with Nexus posting a root-cause hypothesis and its evidence into the incident channel within minutes of declaration. The releases since have been the operational surround: a 24/7 schedule coverage policy that flags gaps before someone is missing from a rotation, more filtering in Insights, escalation reassignment, and now status page updates written by the agent alongside Pingdom uptime metrics and self-serve language settings.

◆ Where it's heading

Two threads are converging. Nexus started inside the incident channel doing diagnosis, and it is now writing the customer-facing artifact as well — the status page is the first place its output leaves the responder's view and reaches the people affected. The rest is steady on-call plumbing: coverage policies, escalation routing, workflow secrets and signing. That split is consistent, with the agent taking judgment work and the platform hardening the mechanics around it.

◆ Prediction

Expect the agent to keep moving along the incident's outward path — customer comms, post-incident drafting — now that it writes to the status page, and expect more policy checks of the schedule-coverage kind that catch gaps before an incident finds them.
