Generating a word cloud (also known as a tag cloud) is a good way to mine internet text. Word (or tag) clouds visually represent the occurrence of keywords found in internet data such as Twitter feeds.
Creating a word cloud using Python and SAS® software was published on SAS Users.Read More
The EFFECT statement is supported by more than a dozen SAS/STAT regression procedures. Among other things, it enables you to generate spline effects that you can use to fit nonlinear relationships in data. Recently there was a discussion on the SAS Support Communities about how to interpret the parameter estimates [...]Read More
מה הסיכוי שאשה שקיבלה תוצאה חיובית בבדיקת ממוגרפיה אכן חולה בסרטן השד? לסיכוי הזה קוראים ערך הניבוי החיובי של הבדיקה, והוא לא תלוי רק בבדיקה עצמה אלא בגורם נוסף.
The post ערך הניבוי החיובי של בדיקת ממוגרפיה לגילוי מוקדם של סרטן השד appeared first on נסיכת המדעים.Read More
I recently wrote about how to use PROC TTEST in SAS/STAT software to compute the geometric mean and related statistics. This prompted a SAS programmer to ask a related question. Suppose you have dozens (or hundreds) of variables and you want to compute the geometric mean of each. What is [...]

The SAS DATA Step's DESCENDING option on BY variables quickly reveals a data set's largest value.Read More
In a previous article, I mentioned that the VLINE statement in PROC SGPLOT is an easy way to graph the mean response at a set of discrete time points. I mentioned that you can choose three options for the length of the "error bars": the standard deviation of the data, [...]

It is always great to read an old paper or blog post and think, "This task is so much easier in SAS 9.4!" I had that thought recently when I stumbled on a 2007 paper by Wei Cheng titled "Graphical Representation of Mean Measurement over Time." A substantial portion of [...]Read More
