Introduction to Approximate Bayesian Computation (ABC)

Darren Wilkinson's blog

Many of the posts in this blog have been concerned with using MCMC based methods for Bayesian inference. These methods are typically “exact” in the sense that they have the exact posterior distribution of interest as their target equilibrium distribution, but are obviously “approximate”, in that for any finite amount of computing time, we can only generate a finite sample of correlated realisations from a Markov chain that we hope is close to equilibrium.

Approximate Bayesian Computation (ABC) methods go a step further, and generate samples from a distribution which is not the true posterior distribution of interest, but a distribution which is hoped to be close to the real posterior distribution of interest. There are many variants on ABC, and I won’t get around to explaining all of them in this blog. The wikipedia page on ABC is a good starting point for further reading. In this post I’ll…

Why I got a statistics masters during my PhD

In this post I talk about my motivation to complete a degree in statistics during my PhD, and all the failures that went into that decision.

Happy New Year!

I hope you had a nice end to 2020, however symbolic that may be. I love making new year's resolutions, although I am over-ambitious, as usual. (I'm still checking things off from 2018, and that's just because its the oldest list I have). 2020 wasn't incredibly productive, but I did accomplish a few things. I… Continue reading Happy New Year!

Beauty and goodness

All in the world recognize the beautiful as beautiful. Herein lies uglinessTao te jing. 2 By defining beauty we necessarily define ugliness, as not beauty or absence of beauty. By defining things that we want, we create the possibility of things we do not want. The Tao urges us to instead appreciate things for what… Continue reading Beauty and goodness

Returning to my pre-grad school interests

Grad school sucked up a lot of my time and energy. At one year from my defense, and 8 months from graduation, I'm ready to get back into some of the things that made me happy. Music Pre grad school, and even pre college, I played violin, clarinet, and piano pretty regularly. I've been practicing,… Continue reading Returning to my pre-grad school interests

Online Community for Modelers: Modeling and Beyond

MODELERS FACE A VARIETY OF CHALLENGES. Although the usefulness and appreciation of modeling as a field is always increasing, modelers today often experience a few setbacks. We often teach ourselves difficult concepts in an effort to innovate along any of the fields we operate in (coding, math, biology, statistics). We may complete our degrees in… Continue reading Online Community for Modelers: Modeling and Beyond
