Happy 🎂 to the normal curve! #OTD 1733 Abraham de Moivre published a description in Latin. It had the catchy title Approximatio ad Summam Terminorum Binomii (a + b)n in Seriem expansi [Approximation of the Sum of the Terms of the Binomial (a + b)n expanded into a Series] 1/2

📘 An interesting initial book release by David Rossell on variable and model selection:

👉 davidrusi.github.io/modelSelecti...

it provides accessible material for students learning the fundamentals of high-dimensional model selection, and it documents the R package modelSelection (formerly mombf).

📅Sep 10, 1885 Francis Galton introduced the idea of regression (toward the mean)

(In his presidential lecture to the Anthropology Section of the British Association, perhaps the most influential such in statistical history)

As I mentioned the other day, I'm very impressed with the new package tinyplot, and it will be my main graphics package going forward.

When I start using a new pkg, I sometimes write up a tutorial, which I've now done for tinyplot,

Las caras de Chernoff, una idea curiosa para representar datos multivariantes, pero que realmente nunca se usó.

Se trata de convertir vectores de datos en caras dada la facilidad de los humanos para identificarlas y compararlas.

The purpose of mathematical models is not to fit to data but to sharpen the questions.
