Small multiples of lineplots > maps (ok, not always, but yes in this case)

Kaiser Fung shares this graph from Ritchie King: Kaiser writes: What they did right: - Did not put the data on a map - Ordered the countries by the most recent data point rather than alphabetically - Scale labels are found only on outer edge of the chart area, rather than one set per panel […]The post Small multiples of lineplots > maps (ok, not always, but yes in this…

Understanding Simpson’s paradox using a graph

Joshua Vogelstein pointed me to this post by Michael Nielsen on how to teach Simpson’s paradox. I don’t know if Nielsen (and others) are aware that people have developed some snappy graphical methods for displaying Simpson’s paradox (and, more generally, aggregation issues). We do some this in our Red State Blue State book, but before […]The post Understanding Simpson’s paradox using a graph appeared first on Statistical Modeling, Causal Inference,…

Construct a stacked bar chart in SAS where each bar equals 100%

I enjoy reading the Graphically Speaking blog because it teaches me a lot about ODS statistical graphics, especially features of the SGPLOT procedure and the Graph Template Language (GTL). Yesterday Sanjay blogged about how to construct a stacked bar chart of percentages so that each bar represents 100%. His chart […]

How literature is like statistical reasoning: Kosara on stories. Gelman and Basbøll on stories.

In “Story: A Definition,” visual analysis researcher Robert Kosara writes: A story ties facts together. There is a reason why this particular collection of facts is in this story, and the story gives you that reason. provides a narrative path through those facts. In other words, it guides the viewer/reader through the world, rather than just throwing […]The post How literature is like statistical reasoning: Kosara on stories.

For background, you can start by reading my recent article, Is It Possible to Be an Ethicist Without Being Mean to People? and then a blog post, Quality over Quantity, by John Cook, who writes: At one point [Ed] Tufte spoke more generally and more personally about pursuing quality over quantity. He said most papers […]The post Am I too negative? appeared first on Statistical Modeling, Causal Inference, and Social…

Color scatter plot markers by values of a continuous variable in SAS

When I visualize three-dimensional data, I prefer to use interactive graphics. For example, I often use the rotating plot in SAS/IML Studio (shown at the left) to create a three-dimensional scatter plot. The interactive plot enables me to rotate the cloud of points and to use a pointer to select […]

Dean Eckles writes: Some of my coworkers at Facebook and I have worked with Udacity to create an online course on exploratory data analysis, including using data visualizations in R as part of EDA. The course has now launched at https://www.udacity.com/course/ud651 so anyone can take it for free. And Kaiser Fung has reviewed it. So definitely feel free […]The post A statistical graphics course and statistical graphics advice appeared first on Statistical Modeling,…

Video: What’s new in SAS/IML 13.1

SAS/IML 13.1 shipped a few months ago. I was asked to produce a video that highlights some of the new features in SAS/IML 13.1. In this video I describe several changes to the language before introducing the new built-in subroutines that create ODS statistical graphs. If your browser does not […]

How to automatically select a smooth curve for a scatter plot in SAS

My last blog post described three ways to add a smoothing spline to a scatter plot in SAS. I ended the post with a cautionary note: From a statistical point of view, the smoothing spline is less than ideal because the smoothing parameter must be chosen manually by the user. [...]
