Agenda and Minutes

1. Announcements
- PT's paper now moved to "printed" status!
2. Updates and status reports
- Student updates: PT was planning to try different window sizes.
- JS will explain in the next meeting what was presented in a potentially relevant PhD proposal presentation last Monday. He may also explain frequentist model averaging.
- DB will invite her to give the talk to us and then we can ask a lot of questions as needed (if she agrees to meet with this group). TC sent the contact info: "Propensity Score Weighting Techniques integration for Population-Based Survey Data with Survival Outcomes: Addressing Missing Data, influential Points, and Assumption Violations" by Xinrui Shi, Ph.D. Student, Applied Statistics (advisor: Wei Zhang).
- Next week TC will give us another rundown on Bayesian model averaging. JS explained some things about Bayesian model averaging last week. Given prior probabilities for each model, use Bayes' theorem to calculate the posterior probability density function. Priors are not always easily available.
- "Bayesian
model
average: A parameter estimate (or a prediction of new observations)
obtained by averaging the estimates (or predictions) of the different
models under consideration, each weighted by its model probability" -

- EG suggested checking Jeffreys prior (https://en.wikipedia.org/wiki/Jeffreys_prior).

3. Reading and discussion
- Readings:
- We have read from https://www.mdpi.com/2077-0383/9/2/572, up to "The second approach focuses on predicting transplant patient survival periods" in section 3. We can continue depending on the attendance profile.
- We can read from https://planet4589.org/space/astro/web/astrolist.html depending on the attendance profile.
- We can continue discussing the "SatType scheme" page
- ... at https://www.planet4589.org
> https://planet4589.org/space/index.html >
https://planet4589.org/space/gcat/web/intro >
https://planet4589.org/space/gcat/web/intro/type.html. We got through
"Byte 4" section, row "E", and can start after that next time.
- NOTE: the "SatType scheme" page describes the column labeled "Type" in the relevant tables, particularly https://planet4589.org/space/gcat/data/cat/satcat.html (thanks to Planet4589 for clarifying this a bit in the documentation).
- We earlier started: https://www.newthingsunderthesun.com/pub/4xnyepnn/release/9. We read up to "In their paper, firms use these technologies to produce a fixed amount of output every period." MC later requested putting our comments in the minutes for later review - good idea. Maybe we can time share across 2 readings next time, and thus get to some material from this source.
- https://towardsdatascience.com/understanding-auc-roc-curve-68b2303cc9c5
might be good to read at some point. We should evaluate that.
- Here are some generic questions about articles (and videos):
- What is the source?
- What is the most significant advance in the human knowledge presented in the paper?
- Why is that advance important?
- What important questions arise from the paper for future research?
- What important questions would it be nice if the paper answered, but does not answer?
- What does the paper present that is novel (no one else has provided that before)?
- What is the relevance of the paper to our satellite research goals?
- Questions from the group?
3. Completed readings include:
- 3/17/23: We read https://planet4589.org/space/astro/web/astrolist.html.
- We finished section 6 of MR paper (C:\Users\jdberleant\Dropbox\research\SpaceTravelMetric-b6-5-16\PapersAndPresentations\byOthers\MatthewRoughanDraft.pdf). This completes the parts that we planned to read.
- Video: https://www.youtube.com/watch?v=S9o66fH_sgo (about MOXIE device which converts CO2 to oxygen). We then read a bit more about MOXIE on wikipedia.
- Https://www.theatlantic.com/science/archive/2019/07/we-need-new-science-progress/594946 on "progress studies." Completed 9/30/22.
- Ryan et al., "A Forgotten Moment in Physiology: the Lovelace Woman in Space Program (1960-1962)", 2009. Completed 7/22/22.
- Various previous papers.
