A semi-professional blog

Miscellanea, poorly written code, and idle thoughts from a trans lady science person. That’s a real thing, right? ¯\_(ツ)_/¯

I’m a big fan of the idea behind the loss of confidence project. The idea is basically that researchers who no longer believe their own published findings can say so without stigma. It’s a nice thought – after all, a non-trivial proportion of the scientific literature is probably incorrect. We could quibble over how much, but really who cares about the number? The point is that it would be nice to know which reported phenomena are genuine and which aren’t.


As my teaching for this terribly full semester starts to wind down1 I’ve been thinking a little about what it means to be a good participant in a group discussion. This isn’t a fully developed blog post, so much as a few thoughts that at some point I’ll develop into a guide for students… Your voice matters! Very often I encounter students who are quiet, thoughtful and tend not to speak much.


’Cause you’re hot then you’re cold You’re yes then you’re no You’re in then you’re out You’re up then you’re down You’re wrong when it’s right It’s black and it’s white - Katy Perry I have mixed feelings about Bayes factors. As Katy Perry once observed, it’s extremely hard to make valid inferences when you aren’t even sure what the hell it is you’re trying to make inferences about.


Sometime back in late April I made a strange decision to try to learn a new R package every day for 100 days. The goal was transparently ridiculous, and even at the time I was aware there was no way I could do it. Of course “a package every day” was never the primary goal. What I’d really hoped to do is get into the habit of trying out new R packages, just for my own curiosity.


I’m getting to the very end of this package tryout exercise, and I suspect this will be the last post (other than perhaps a wrap up on Friday). It’s been a mildly annoying morning: I’ve done something to my foot, I’ve been awake since 4am, and somehow my twitter feed was full of people talking about Jordan Peterson 😒 Sigh. I probably should have just blocked or muted everyone talking about him rather than engage, but what’s done is done and I’d like to enjoy the rest of my morning.



Brownian bridges

This was a series of animated GIFs I made using gganimate. The path of each dot is sampled using a Brownian bridge, used to interpolate stochastically between fixed frames

Bayesian rain

This started out as an attempt to mimic Tom Griffiths’ lab logo using ASCII characters rather than MNIST digits, as a way of teaching myself the imager package, and then it got a little silly.
