What is Displayr?

Chat is being made legible while the survey-analysis core picks up the fundamentals it lacked.

Displayr is shipping on two fronts at a steady, unhurried cadence. The AI assistant is being made auditable rather than more capable — a context pill showing exactly what a prompt will send, a change summary listing every item Chat added, edited or deleted, and an Explain This button that routes errors and warnings into Chat with context attached. Separately the document core is filling in fundamentals: controls that stay synced across pages and page masters, rolling averages computed on date-keyed tables, browser-style back and forward navigation, and templates that can be saved as folder-scoped defaults.

What is loo?

loo keeps rewriting the diagnostics Bayesian modellers read off model comparison

loo computes leave-one-out cross-validation and model comparison for Bayesian models in the Stan ecosystem. Two releases in this window changed what users actually read: 2.7.0 replaced the fixed Pareto-k thresholds with sample-size-dependent ones and dropped the middle category, and 2.10.0 reshaped loo_compare's output into a data.frame with new uncertainty columns. The releases between are diagnostic robustness fixes and moment-matching corrections.

5.0

Chat is being made legible while the survey-analysis core picks up the fundamentals it lacked.

◆ Current state

Displayr is shipping on two fronts at a steady, unhurried cadence. The AI assistant is being made auditable rather than more capable — a context pill showing exactly what a prompt will send, a change summary listing every item Chat added, edited or deleted, and an Explain This button that routes errors and warnings into Chat with context attached. Separately the document core is filling in fundamentals: controls that stay synced across pages and page masters, rolling averages computed on date-keyed tables, browser-style back and forward navigation, and templates that can be saved as folder-scoped defaults.

◆ Where it's heading

The Chat work reads as a deliberate answer to the trust problem with AI in analyst tools — every release makes what the assistant touched inspectable rather than expanding what it can do unprompted. The other track is closing gaps a long-standing survey analysis platform accumulates, with the default-template mechanic notable for scoping defaults by Cloud Drive folder, which turns a personal preference into an organizational standard. Neither track has produced a directional move in this window.

◆ Prediction

Expect the transparency pattern to extend to Chat actions that modify data rather than layout, since the change summary establishes the mechanism. Folder-scoped defaults look like the start of broader template governance.

loo keeps rewriting the diagnostics Bayesian modellers read off model comparison

◆ Current state

loo computes leave-one-out cross-validation and model comparison for Bayesian models in the Stan ecosystem. Two releases in this window changed what users actually read: 2.7.0 replaced the fixed Pareto-k thresholds with sample-size-dependent ones and dropped the middle category, and 2.10.0 reshaped loo_compare's output into a data.frame with new uncertainty columns. The releases between are diagnostic robustness fixes and moment-matching corrections.

◆ Where it's heading

The package is being brought in line with the current PSIS literature rather than extended with new features, and the practical effect is that the numbers practitioners quote in papers keep changing meaning. Work is increasingly delegated to posterior for shared computations, and the project has added contributor process, benchmarks and a published AI contribution policy.

◆ Prediction

Expect further work on comparison diagnostics — the p_worse and diag_* columns are new enough that their defaults and documentation will likely be revised next.
