Strengthen your programming skills with tips and techniques from the experts
Getting started with SAS Viya and RStudio -- making the connection, and submitting my first commands via CAS actions.
Which character variables have the highest frequency count? You can easily determine this using a variety of procedures that calculate frequency count. For example, the FREQ Procedure or the MEANS Procedure. This blog post illustrates this process through two examples.
See how to sample unstructured (text) data using SAS Viya and CAS actions. This post includes complete code to cluster the text documents via k-means, and treats the cluster memberships as strata for analysis.
SAS batch jobs can generate many log files that accumulate over time. In this post, we present a SAS program that cleans up old log files on your system.
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
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
There are many ways to avoid transcoding problems when you have national language characters in SAS programs that you save from a SAS®9 (English) session and move to a UTF-8 environment. In this article, we'll share tips to help you avoid such issues.
To reference CAS tables using a one-level name we will issue two statements that alter which libref houses the tables referenced as one-level names.
Cloud Analytic Services (CAS) is really exciting. It’s open, multi-threaded and distributed. And, best of all for SAS programmers, it’s SAS. You can even run DATA Step in CAS. Here's more on how DATA Step work in a multi-threaded, distributed context.
SAS Studio is the latest way you can access SAS. This newer interface allows users to reach SAS through a web browser, offering a number of unique ways that SAS can be optimized. At SAS Global Forum 2018, Lora Delwiche and Susan J Slaughter gave the presentation, “SAS Studio: A New Way to Program in SAS.” This post reviews the paper, offering you insights of how to enhance your SAS Studio programming performance.
