Every now and then I want to generate normally distributed values in something like Perl, which does not have built-in functions for it. Unfortunately, there’s no easily remembered way to generate numbers from the normal distribution. I just learned the best way to do it: don’t. Generate logistically distributed values instead.
KONKRET GRANSKNING. En vanlig missuppfattning är att migrationspolitiken har varit för generös i landet, eller att migrationen har varit ”okontrollerad”. Som framgår av offentligt tillgänglig statistik så har bara en liten del av alla uppehållstillstånd gått till flyktingar och asylsökande

This book will teach you how to do data science with R: You’ll learn how to get your data into R, get it into the most useful structure, transform it, visualise it and model it. In this book, you will find a practicum of skills for data science. Just as a chemist learns how to clean test tubes and stock a lab, you’ll learn how to clean data and draw plots—and many other things besides. These are the skills that allow data science to happen, and here you will find the best practices for doing each of these things with R. You’ll learn how to use the grammar of graphics, literate programming, and reproducible research to save time. You’ll also learn how to manage cognitive resources to facilitate discoveries when wrangling, visualising, and exploring data.
El Objetivo del paquete aprendeR es facilitar que nuevas personas puedan R moderno con una curva de aprendizaje baja, y evitando que el inglés sea una barrera para que se puedan centrar en el aprendizaje competencial de R. Se incluyen traducciones al castellano de tutoriales presentes en otros paquetes (learnr, tutorial.helpers, r4ds.tutorials, ...), y eventualmente nuevos tutoriales más adelante.
