Monthly Math development meeting: 04/15/2021, 10 am EDT

Sorry for the late notice. This is happening today in about 2 hours!

Hey all, we’ve been having monthly Math meetings on the third Thursday of the month. The next one is tomorrow, April 15, 2021, at 10 am EDT.

This will last no more than one hour; if we need more time, we will schedule additional time.

This meeting is open to all those that currently contribute to the Math library or that would like to contribute to the Math library. If you’d like an invite to the Google Calendar event, please DM me with your Google handle. If you’d like to just have a copy of the event on your calendar, please use this link:

  • this is a chance to collaborate and coordinate efforts. We’re expecting everyone to be kind and courteous. And patient. We have a team with diverse backgrounds.
  • impactful decisions will not be made at these meetings. That will continue to be done online on these forums. The meetings are a good time to discuss and get on the same page, but the decision making will be done online where we can include the opinions of others that can’t make the meeting.
  • important discussions that happen at the meeting will be communicated back online on these forums. If they don’t make it back here, it wasn’t important. No one will be penalized for not being present at a meeting.

If there’s anything you know you want to talk about, please post here. This is a good time to request help from others if there’s expertise that you need.

@spinkney, @stevebronder, @wds15, and I are on right now.

We don’t have a set agenda; we’re discussing some of the voting procedures.

@wds15 talked us through about the PR from @yizhang on the ode testing.

@wds15 is excited about the adjoint ODE.

@spinkney is walking us through the new issues he’s posted about copulas.

We’re talking about Request for vector return from normal_cdf given vector arguments · Issue #2468 · stan-dev/math · GitHub. This is asking about returning vectors from vectorized cdf functions. @stevebronder, @wds15, and I discussed some of the implementation points. One of us will post a summary of that on the issue.

Meeting adjourned.
