Feature request: custom pillar formatting for diagnostic columns

10

I believe that the pillar package (used by tibble) permits custom colors, in which case it would be useful to color the contents of the diagnostics columns (rhat, bulk_ess, tail_ess)...

Consider using progressr for compile progress indicator (possibly others?)

The latest release added a spinner when compiling, which is nice but adds spam when sinking output to file in quasi-interactive sessions (been playing with SBC a bunch lately). I...

Recompile only on changes to output of stanc3 auto-formatter (feature request & design discussion)

(While an issue already exists related to this, as well as a PR, I thought it would be cleaner to start a new issue to discuss things now that I've...

Better progress indicators (feature request & design discussion)

5

At present, progress is indicated by simply printing the stdout of cmdstan, which is somewhat difficult to parse visually and spams the console with lots of lines. Better would be...

Background/asynchronous sampling (feature request & design discussion)

11

I propose modification of the various run methods to enable doing so in the background rather than occupying the foreground R session. This is useful for scenarios where one wants...

Adding a `sampling_GQ` argument to `sample()` (feature request & design discussion)

1

Similar to the [FR](https://github.com/stan-dev/cmdstanr/issues/427) to have a `warmup_GQ` argument, it would be useful to have an argument to turn on/off the running of the GQ section during sampling. For example,...

Adding a `warmup_GQ` argument to `sample()` (feature request & design discussion)

While I understand that the Generated Quantities section does not get run during warmup if `save_warmup=FALSE`, there are reasons to want the parameter values from warmup but not want to...

At present, sampling is terminated when a criterion number of post-warmup samples have been obtained. Given implementation of [during-sampling diagnostics](https://github.com/stan-dev/cmdstanr/issues/425), it would be possible to change this termination rule to...

During-sampling diagnostics (feature request & design discussion)

2

I propose to add optional computation of diagnostics during sampling. To achieve this, I propose to read the csv files to: (1) track the proportion of treedepth exceeded (2) track...

Any way to inform ETA estimate with prior info?

3

I'm working on a pipeline-prototyping package that uses progressr to track progress as many elements of a list are processed and where efficient re-processing is enabled by skipping over already...
