Repeated measures When time is one of the factors

Repeated measures are one of the most commonly misunderstood topics in statistics, and here I will show how to handle them in Python using Bambi and PyMC.

Bonus: to categorize or not to categorize continuous variables such as age?

Pierre Alquier (ESSEC) - PAC Bayes: introduction and overview
YouTube video by Post-Bayes seminar Pierre Alquier (ESSEC) - PAC Bayes: introduction and overview

The 3rd chapter of the "post-Bayes" seminar, focused on PAC-Bayes bounds, started yesterday. I gave a very introdutory talk, which is already on Youtube.

There will be 5 more talks in this chapter, see the full schedule there: postbayes.github.io/seminar/

D'accordo su tutto, ma credo anche che uno le cause se le debba scegliere, altrimenti ci sarebbero Palestina, Ucraina, Sud Sudan...
Mi pare piu' sensato focalizzarsi su qualcosa su cui si puo' fare la differenza e provare a cambiare le cose. E con Putin non vedo come sia applicabile.

Ig Nobel Prize: Germans speak better Dutch when they drink alcohol - Delta Researchers from Maastricht won the Ig Nobel Peace Prize Thursday night for their discovery that alcohol can help people speak another language, particularly when it comes to pronunciation.

I'm saying this for years, and finally someone proved it!

Completely randomized design When only one factor is relevant

Another blog post on a personal experiment: finding the faster algorithm using a completely randomized design.

Why? Computational experiments are fast and cheap, they are an easy way to learn experiment design principles in a hands-on way.

My preference is similar for similar reasons.

100% agree, that would be a promising combination! unfortunately most ML people (afaik) have little or no knowledge about experimental design
