Ecological Statistics. I came for the charismatic megafauna and stayed for the problematic megamodels. Skeptic.

Cluster SCR model for perfectly aggregated and cohesive groups where you observe individual ID but not group ID. Pretty sure. 😄

I have TWO graduate openings (one M.S. and one Ph.D.) in @The_SPEC_Lab , both within our mountain lion program. 🦁 Deadline to apply is June 7:

MS position in noninvasive monitoring strategies: https://t.co/vZH1e0YTIO

PhD position in density estimation:

Added a more rigorous description of my N-prior data augmentation approach

Matern Type III repulsive point processes in NIMBLE. Pretty cool approach and does not require a birth-death process for estimation, so it is fast and mixes well. Can add SCR observation model.

Okay MIT needs us to do "internship" (broadly defined) can be simply a collaborative project that is publishable. Anyone in industry wants to collaborate?

Figured out how this data augmentation approach to is related to that presented by Schofield and Barker (2014). Theirs can be specified with bugs code, which is very slick! As coded, mine runs 2x as fast with better ESS/iteration. Cool stuff. More formal details soon.

Marginal version of SMR with interspersed marking and sighting and all sample types is pretty slick.

[Ben Augustine @BenCAugustine]

Split out all my SMR models marginalizing over latent IDs with Herliansyah et al. (2024) efficiency trick into their own repository. Premarked, interspersed marking/sighting, natural marks. single and multi session, Dcovs, habitat masks. Count prior data augmentation.

[Ben Augustine @BenCAugustine]

@chrissuthy Absolutely, but can't relocate to St. Andrews. Will send you an email.

[Ben Augustine @BenCAugustine]

Top 5 things I want to write up from my Github repositories. Someone hire me for a while and we can pump these out. Will describe some more later.

@DrJulieKYoung @MichiganDNR independence violation! lol

[Ben Augustine @BenCAugustine]

@realHollanders I asked it how to do a particular update that I believe is computational infeasible

[Ben Augustine @BenCAugustine]

😂

[Ben Augustine @BenCAugustine]

@realHollanders I think it may be feeding me things I said in the appendix of a preprint

Put some more work into the data aug approach I've been using. Have 3 ways to do the N/z updates now. I think "count prior data augmentation" is a good name for it (besides data benaugmentation 😆). I've sloppily said this is RJMCMC sometimes in the past, but it is def data aug

Pop simulator with hab and D effects on repro, survival, and movement. Females only. Grey: 95% HR. Survival: red dots adult deaths, gold, 1 or more dependent deaths. Movement, red is adult HR relocation, gold subadult dispersal. Reproduction: gold indicates a new litter.
