Using and Abusing Data Visualization: Anscombe’s Quartet and Cheating Bonferroni

Anscombe’s quartet comprises four datasets that have nearly identical simple statistical properties, yet appear very different when graphed. Each dataset consists of eleven (x,y) points. They were constructed in 1973 by the statistician Francis Anscombe to demonstrate both the importance of graphing data before analyzing it and the effect of outliers on statistical properties.Let’s load and view...

Customer segmentation – LifeCycle Grids, CLV and CAC with R

We studied a very powerful approach for customer segmentation in the previous post, which is based on the customer’s lifecycle. We used two metrics: frequency and recency. It is also possible and very helpful to add monetary value to our segmentation. If you have customer acquisition cost (CAC) and customer lifetime value (CLV), you can easily... Read More »

Waterfall plots in R

Follow Email Last week I posted about an orphaned paper of mine, a piece of research that hasn’t yet found a home and which I’m unlikely to find further time to work on. Abandoning something that you’ve worked hard on is disappointing and so it made sense to release it for those who were interested.

A “Startlingly Neat & Simple” Rule & Five Graphs About Patterns That Might Surprise You

George Zipf popularized an idea—Zipf’s Law—that approximates populations of cities, distribution of money in counties, and how frequently words are used. Nobel Prize-winning columnist Paul Krugmans wrote of Zipf’s Law that “the usual complaint about economic theory is that our models are oversimplified — that they offer excessively neat views of complex, messy reality. [In the case of...

The idea of using these metrics comes from the RFM analysis. Recency and frequency are very important behavior metrics. We are interested in frequent and recent purchases, because frequency...

We were looking for a different type of visualization for a project at work this past week and my thoughts immediately gravitated towards streamgraphs. The TLDR on streamgraphs is they they are generalized versions of stacked area graphs with free baselines across the x axis. They are somewhat controversial but have a “draw you in”
