Advanced ODS Graphics: PROC SGPLOT, BY groups, and SG annotation

You can use PROC SGPLOT, BY variables, and a SG annotation data set together to put separate annotation into each BY group. However, you need two more steps to make it happen. This post shows all of the steps necessary to put different annotations in... Read More

How old is your county?

The United States declared independence in 1776, and we celebrate it on July 4th every year. But the land areas that make up the United States today weren't necessarily the same as they were back then. So I thought it would be interesting to create a m... Read More

How to calculate Word Mover's Distance with SAS

Word Mover's Distance (WMD) is a distance metric used to measure the dissimilarity between two documents, and its application in text analytics was introduced by a research group from Washington University in 2015. The group's paper, From Word Embeddings To Document Distances, was published on the 32nd International Conference on Machine [...]

The probability that two random chords of a circle intersect

In a previous article, I showed how to find the intersection (if it exists) between two line segments in the plane. There are some fun problems in probability theory that involve intersections of line segments. One is "What is the probability that two randomly chosen chords of a circle intersect?" [...]

No typical SAS user: how three professionals prep data using SAS

Did you know that 80 percent of an analytics life cycle is time spent on data preparation? For many SAS users and administrators, data preparation is what you live and breathe day in and day out. Your analysis is only as good as your data, and that's why we wanted [...]

The intersection of two line segments

Back in high school, you probably learned to find the intersection of two lines in the plane. The intersection requires solving a system of two linear equations. There are three cases: (1) the lines intersect in a unique point, (2) the lines are parallel and do not intersect, or (3) [...]

תאונות הדרכים בישראל – לפני ואחרי מינוי של ישראל כץ לשר התחבורה

בתקופת כהונתו של ישראל כץ כשר התחבורה, עד סוף 2017, הואטה מגמת הירידה החדה בשיעורי תאונות הדרכים עם נפגעים שהתרחשה בין 2003 ל-2009. הירידות בשיעורי תאונות הדרכים הקשות והקטלניות נבלמו כמעט לחלוטין, ואף יש מגמת עליה בכמות תאונות הדרכים הקשות.

Using %IF-%THEN-%ELSE in SAS programs

SAS programmers have long wanted the ability to control the flow of their SAS programs without having to resort to complex SAS macro programming. With SAS 9.4 Maintenance 5, it's now supported! You can now use %IF-%THEN-%ELSE constructs in open code. This is big news -- even if it only [...]

How to get N-grams and TF-IDF count from Chinese documents

SAS Visual Text Analytics provides dictionary-based and non-domain-specific tokenization functionality for Chinese documents, however sometimes you still want to get N-gram tokens. This can be especially helpful when the documents are domain-specific and most of the tokens are not included into the SAS-provided Chinese dictionary. What is an N-gram? An [...]

Compute derivatives for nonparametric regression models

SAS enables you to evaluate a regression model at any location within the range of the data. However, sometimes you might be interested in how the predicted response is increasing or decreasing at specified locations. You can use finite differences to compute the slope (first derivative) of a regression model. [...]
