Have 5-minutes? Then let’s learn time series. In this short articles series, I highlight how you can get up to speed quickly on important aspects of time series analysis. Today we are focusing on the most fundamental tool, the time plot. Learn how to...

When answering an X validated question on running an accept-reject algorithm for the Gamma distribution by using a mixture of Beta and drifted (bt 1) Exponential distributions, I came across the above glitch in the fit of my 10⁷ simulated sample to the target, apparently displaying a wrong proportion of simulations above (...

This report describes improvements to clipping in the R graphics engine. These changes will be of particular interest to maintainers of R graphics device packages ...

In this post, we’ll take a look at a basic text visualization technique we’ve seen elsewhere on this blog: word clouds. There are lots of great text analytics tools in R for this, and the process of making a basic word cloud is very straightforward...

Introduction 2 different scenarios Independent samples Paired samples Introduction In a previous article, we showed how to compare two groups under different scenarios using the Student’s t-test. The Student’s t-test requires that the distrib...

Introduction 2 different scenarios Independent samples Paired samples Introduction In a previous article, we showed how to compare two groups under different scenarios using the Student’s t-test. The Student’s t-test requires that the distributions follow a normal distribution1. In this article, we show how to compare two groups when ...
