🕵️ El sesgo de selección es la madre de todos los sesgos.
Porque tu investigación podría estar condenada antes de empezar.

Hoy hablamos del sesgo de selección, ese enemigo silencioso que distorsiona estudios académicos y decisiones de negocio. 👇

✨Hey fellow R stats enthusiasts!

🥳 I just published a detailed analysis on manual gradient calculation in HMC on my blog, Bayesically-Speaking 🚀

🧐 We cover the necessary math and partial derivatives that guides the sampler.

@DigestData @SolomonKurz It seems I lost the opportunity to write it good (pun intended). Thanks for the kind comment!

[Matías Castillo-Aguilar @matias_science]

@ChelseaParlett Nothing like some NUTS in your HMC

[Matías Castillo-Aguilar @matias_science]

Desarrollé un artículo detallando el proceso de modelar la neuroplasticidad sináptica a través de las matemáticas!

Los invito a descubrir de qué manera esto es posible, en el siguiente enlace:

We are giving away a signed copy of new 2nd Edition of 'Analysis of #CategoricalData with #RStats' by @Chris_Bilder and @TomLoughin. Just like, repost, and follow to be in with a chance! Winner announced on Monday. https://t.co/Fc3cPuU8DE #Statistics #DataScience @CRC_MathStats

Don't believe me?

Grab any medical research paper, and I guarantee you this copy pasta is in that paper.

Parece chiste pero no… pagar por poder tener un PDF de tu propia investigación y poder compartirselo a 25 personas… #Elsevier

[Eiko Fried @EikoFried]

For only $143, Elsevier/Springer will send me a PDF of my accepted paper that I can share with 25 people :).

Publishers again adding tremendous value. I wouldn't know what to do without this attractive option.

[Matías Castillo-Aguilar @matias_science]

@ChelseaParlett Oh god yes…

At first, is like: “here is some simple Bayesian linear regression”… 🤝

Then you get: “Build your own symplectic integrator for Hamiltonian systems” 💀

[Mattan S. Ben-Shachar @mattansb]

Why do reviewers ask for a power analysis to justify the sample size *after* the study has completed?

Can you have an a priori power analysis post study? It this necessary?
IMO no.

Beautiful visualization of a random effects meta análisis!

[Matías Castillo-Aguilar @matias_science]

@rlmcelreath Richard, you have already done a lot for the field. I think that you are the least to owe anything to the academia. Mi prior guess (wink wink) is that you’ll do more than fine in the industry

[Matías Castillo-Aguilar @matias_science]

I have developed an R package that provides tools for 2D gait data analysis and motion capture.

This package also offers tools to create informative visualisations with many functionalities.

Dear fellow #Rstats and #Bayesian geeks. Have you ever tried to wrap your head around Hamiltonian Monte Carlo (HMC), discovering it was a math nightmare?

No worries cause I got your back covered. I’ve written a blog explaining the intuition behind HMC:

Habiendo trabajado extensivamente con ambos paradigmas estadísticos, puedo decir sin lugar a dudas que la la estadística Bayesiana es mi marco de análisis favorito

[Matt Dancho (Business Science) @mdancho84]

Bayesian data analysis is a fundamental concept in data science. But it took me 2 years to understand its importance.

In 2 minutes, I'll share my best findings over the last 2 years exploring Bayesian Modeling.

Let's go. 🧵

@ChelseaParlett The love is in the parameter space… I mean…! In the air
