Ari Lamstein writes: I chuckled when I read your recent “R Sucks” post. Some of the comments were a bit … heated … so I thought to send you an email instead. I agree with your point that some of the datasets in R are not particularly relevant. The way that I’ve addressed that is […] The post Some U.S. demographic data at zipcode level conveniently in R appeared first…

An exciting new entry in the “clueless graphs from clueless rich guys” competition

Jeff Lax points to this post from Matt Novak linking to a post by Matt Taibbi that shares the above graph from newspaper columnist / rich guy Thomas Friedman. I’m not one to spend precious blog space mocking bad graphs, so I’ll refer you to Novak and Taibbi for the details. One thing I do […] The post An exciting new entry in the “clueless graphs from clueless rich guys”…

Append data to add markers to SAS graphs

Do you want to create customized SAS graphs by using PROC SGPLOT and the other ODS graphics procedures? An essential skill that you need to learn is how to merge, join, append, and concatenate SAS data sets that come from different sources. The SAS statistical graphics procedures (SG procedures) enable […] The post Append data to add markers to SAS graphs appeared first on The DO Loop.

Highlight forecast regions in graphs

A SAS customer asked how to use background colors and a dashed line to emphasize the forecast region for a graph that shows a time series model. The task requires the following steps: Use the ATTRPRIORITY=NONE option on the ODS GRAPHICS statement to make sure that the current ODS style […] The post Highlight forecast regions in graphs appeared first on The DO Loop.

Visualize the ages of US presidents

Who was the oldest person elected president of the United States? How about the youngest? Who was the oldest when he left office? Let's look at some data. Wikipedia has a page that presents a table of the presidents of the US by age. It lists the dates for which […] The post Visualize the ages of US presidents appeared first on The DO Loop.

Visualize a torus in SAS

This article uses graphical techniques to visualize one of my favorite geometric objects: the surface of a three-dimensional torus. Along the way, this article demonstrates techniques that are useful for visualizing more mundane 3-D point clouds that arise in statistical data analysis. Define points on a torus A torus is […] The post Visualize a torus in SAS appeared first on The DO Loop.

Rotation matrices and 3-D data

Rotation matrices are used in computer graphics and in statistical analyses. A rotation matrix is especially easy to implement in a matrix language such as the SAS Interactive Matrix Language (SAS/IML). This article shows how to implement three-dimensional rotation matrices and use them to rotate a 3-D point cloud. Define […] The post Rotation matrices and 3-D data appeared first on The DO Loop.

No evidence shark attacks swing elections

Anthony Fowler and Andy Hall write: We reassess Achen and Bartels’ (2002, 2016) prominent claim that shark attacks influence presidential elections, and we find that the evidence is, at best, inconclusive. First, we assemble data on every fatal shark attack in U.S. history and county-level returns from every presidential election between 1872 and 2012, and […] The post No evidence shark attacks swing elections appeared first on Statistical Modeling, Causal…

Ahh, that’s smooth! Anti-aliasing in SAS statistical graphics

I've written several articles about scatter plot smoothers: nonparametric regression curves that reveal small- and large-scale features of a response variable as a function of an explanatory variable. However, there is another kind of "smoothness" that you might care about, and that is the apparent smoothness of curves and markers […] The post Ahh, that's smooth!
