Why analytical models are better with better 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 a 3-D rotation matrix
In three dimensions there are three canonical rotation matrices:

That’s why the options to change the statistics shown in the crosstab are at the top of Categorical’s red triangle menu. That’s why the new “Redo” and “Save Script” buttons are always in the same spot. But there are always some neat features that I wish I could make more prominent. This blog series will show off a few of them, starting with Aligned Responses. Many surveys have questions about ... Read More

Your chance to vote … for your favorite election graph!

Feed: SAS BlogsRSS – SAS Blogs. Author: Robert Allison. Elections in the US are a 'target rich environment' for data analysts. There are surveys and forecasts before the election, and the presentation of results during and after the voting. What's your favorite election-related graph of all time?

But the Fourth Industrial Revolution requires further development of consumers’ willingness to share data. That data is needed to fuel the hyper-personalised services that technology can deliver. As our research with Future Foundation indicates, ... Read More
