I’ve just made some Bayesian Statistics tutorials using Julia and Turing. The content is fully opensourced in GitHub and has a very permissive Creative Commons License (which means you can copy and alter the crap out it…). My hope is to have more people into Bayesian statistics. The content is aime…

I have a new content that is an open-access creativecommons graduate course on Bayesian statistics. There is Stan and Turing code for tons of models, along with 340+ slides. [image] GitHub - storopoli/Bayesian-Statistics: This repository holds slides and code... This repository holds s…

[image] ForceBru: What’s a “weekly informative prior towards a “fair” dice”? This is going to be philosophical question? I don’t know, i think a 6-length vector of 1/6? [image] ForceBru: Why do we choose Dirichlet(6, 1) and not, say, Dirichlet(6, 8) ? As far as I can tell, all of them ha…

Dirichlet(6,8) implies you are quite confident that it’s a fair dice roll. Whereas (6,1) says “I don’t really know”

The alpha in a Dirichlet is a “concentration”. Maybe this helps: julia> std(rand(Dirichlet(6,1),1000),dims=2) 6×1 Matrix{Float64}: 0.14305158706755236 0.14043323912305447 0.12959278663394877 0.14360349478154502 0.14403746553339422 0.13586448356346292 julia> std(rand(Dirichlet(6,8),1000),dim…

[image] Storopoli: i think a 6-length vector of 1/6? Oh, I thought that was a term that I didn’t understand. I messed around with the Dirichlet distribution at https://ben18785.shinyapps.io/distribution-zoo/ , and it looks like when the vector of parameters is all ones, like Dirichlet(ones(3)…

Yeah I was aiming for a uniform flat distribution. And also what a great demonstration by @cscherrer thanks!

BTW, @Storopoli , these are really nice tutorials - way easier to understand than those in Turing’s documentation. So thank you!

Hey @ForceBru thanks! I was invited to give a talk to Stuttgart’s Julia Meetup Group ( Login to Meetup | Meetup ) I will cover some stuff that I haven’t gone on the tutorials. It will be next Saturday and open to everybody. Will be in english. Edit: I’ve found that Turing’s examples are more geared …

Cool, just signed up for the talk!

updated link here: Bayesian Statistics using Julia and Turing

Hi @Storopoli I a new user of Turing and Julia for Bayesian modeling. I was trying to replicate a basic Linear Regression model in your GitHub link (Children’s IQ Score example). I could replicate the model but could not plot the posterior results / trace using StatsPlots. When I type using StatsPl…
