Calibration curves for simulation-based inference: bringing ML diagnostics to fisheries stock assessment

Fisheries science leans heavily on simulation and estimation, and deserves a shared way to communicate the tradeoffs between model performance and confidence. It’d also be…

Linking Spatial Processes to Covarying Paramters

There are lots of real-life processes that we know are driven by the environment, and exhibit covariance amongst the parameters we use to model them. People interested in…

Unusual Grad School Advice

I’ve been ambivalent about writing graduate school “advice”, given that 1) I’m barely out of it and 2) tons of others have done so. What could I add?

Ageing Error Matrices - some notes

I revisit the inclusion of ageing error matrices frequently enough that I wanted to consolidate some notes here. None of this is new information; it is a resource for myself…

Leveraging try_again() for error catching in MSEs

This post is not a full breakdown of how to structure code for Management Strategy Evaluation (MSE) work. I’m certainly not a pro software engineer. Instead, I was pleased…

Length-based Processes in an Age-Structured Model

This is in the category of “stuff I thought I understood” until I didn’t.

How I Keep Up With the Literature

My lab recently had a meeting where we discussed the nuts & bolts of performing a peer-review for a journal article, which got everyone talking about their preferred methods…

How Do Recruitment Deviations Work?

For an in-depth description of the theory and math behind recruitment deviations in assessment models, check out: Methot, R.D., Taylor, I.G., Chen, Y., 2011. Adjusting for…

Why do we use ln(19)?

Have you ever noticed that sneaky \(log(19)\) in your logistic equation for maturity or selectivity? What is up with that?

How I studied for my PhD General Exam

I am finally a PhD Candidate! You may want to check out my “How I studied for my PhD Quals” post, which detailed my prep for a 5-day written examination I took in December.…

Some Algebra for Equilibrium Recruitment

I often find myself revisiting the various “re-arrangements” of the Beverton-Holt stock-recruitment relationship, particularly when moving between equilibrium quantities. I…

How I studied for my PhD qualifying exam

Yay, I got a high pass on my exam (now back to the things I neglected Autumn quarter). Before I disappear, I wanted to share how I went about studying for my exam, in hopes…
