The Online MCMC

I'm an online portal for performing parameter estimation via Markov chain Monte Carlo

[The Online MCMC @theonlinemcmc]

It even shows an example using TheOnlineMCMC!

My excellent @LancUniPhysics summer intern Mo Ghani has produced a great webpage showing the use of a variety of Python-based #Bayesian inference packages on real physics/astronomy datasets https://t.co/8Mznc7oyUR #mcmc #nestedsampling

@exoplaneteer @pymc_devs @kylebarbary If anyone wants to try and it, please do, and send me any feedback/comments/suggestions via the code's github repo here https://t.co/l32Fcrgpg2

It's been a while coming, but I've finally got round to updating https://t.co/ZzwDO9Aggi (thanks to the effort of a great undergrad project student) - it now uses the bilby package (https://t.co/8cJqRO6pzj) as the back-end... (1/n)

[The Online MCMC @theonlinemcmc]

and thanks to bilby's interface the website now allows you to choose between the emcee (@exoplaneteer) and PyMC3 (@pymc_devs) MCMC-based algorithms, and the dynesty and nestle (@kylebarbary) nested sampling based algorithms (2/n)

[Matthew Pitkin @matt_pitkin]

I created a webpage with a simple demonstration example (fitting parameters of a straight line) of using of four Python-based #MCMC packages, and five Python based #NestedSampling packages #bayes https://t.co/kMBwtDrCQo. Details on which ones to follow...

@pymc_devs @mcmc_stan @colindcarroll @AustinRochford Thanks. Our site is fairly basic at the moment, but a proper API would very be nice to have in the future. Please do ask me (aka @matt_pitkin) any questions, and I'm more than happy to exchange ideas.

[The Online MCMC @theonlinemcmc]

Now I've also got the example using #CPNest (https://t.co/f1aQbyVz1y) @JohnVeitch https://t.co/eHU4Hy8bUm https://t.co/phQAyQAhZm to add some #NestedSampling into the mix!

[The Online MCMC @theonlinemcmc]

We'll hopefully be adding samplers other than #emcee soon-ish. As such, to figure out how to code them up, I've attempted a toy example using #PyMC3 @pymc_devs ()https://t.co/wfFiuwTwU9 and #PyStan @mcmc_stan (https://t.co/fRTUsN74L2)

[The Online MCMC @theonlinemcmc]

The site (https://t.co/ZzwDO9Aggi) has a new, and hopefully improved, look. You can also find a video demonstration of how to use it here https://t.co/ZdlJftNYVI. Please let me know what you think of the new layout. #mcmc #bayes #inference

Researchers at our @UofGravity and @UofGPhysAstro will benefit from a £500k bequest from pioneering physicist Prof Ronald Drever: https://t.co/aZNQTLBe6s

I've been working on the first major release of emcee in years & it's ready for testing: https://t.co/FBbwSG6OIR

[The Online MCMC @theonlinemcmc]

We'd like some feedback for https://t.co/ZzwDO9Aggi. If you'd like to try it please consider filling in this form https://t.co/mSRVsiNemJ

[Dan F-M @exoplaneteer]

The MCMC tutorial that @davidwhogg wrote (with tiny contributions from me) is posted & submitted to @AAS_Publishing: https://t.co/jWZmMAx59t

[The Online MCMC @theonlinemcmc]

@Dr_CMingarelli @JohnVeitch Indeed he has https://t.co/WkTccVSmIk

[The Online MCMC @theonlinemcmc]

a python nested sampling package, cpnest, by @JohnVeitch and Del Pozzo (https://t.co/phQAyQAhZm) is now on PyPI. 'pip install cpnest' away!

[The Online MCMC @theonlinemcmc]

Here's a nice overview of #MCMC methods (and, in particular, their use in astronomy) https://t.co/HFeUehMP3B #Bayesian

[The Online MCMC @theonlinemcmc]

The parameters for #GW170104 are estimated using MCMC/(nested sampling) algorithms like me

If you have any technical suggestions (bug reports, enhancements, etc) then you can also add them here https://t.co/wauy4llOm0

[The Online MCMC @theonlinemcmc]

The site is still undergoing testing, but please feel free to give it a go and send me any feedback https://t.co/ZzwDO9Aggi

[The Online MCMC @theonlinemcmc]

It took longer than hoped, but finally "The Online MCMC" is now back online (and hosted by @uofgphysastro) https://t.co/ZzwDO9Aggi
