In SAS Visual Analytics 8.3, a Data View is a reusable and shareable template for a data source. That means that the data view is tied to the data source, and not to the report. Here's how to use them.
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
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
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
Introduced with Visual Analytics 8.2 is a new object named: Key Value. The intent of this object is call attention to an aggregated value for a measure, a category, or both. In this post you'll learn more about working with the Key Value Object in SAS Visual Analytics.
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.
This post addresses connecting to SAS Viya using a One-Time-Password generated by SAS 9.4. We'll learn more about SAS Viya connecting with SAS 9.4 and talk about how this authentication flow operates and when we are likely to require it.
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.
In SAS Visual Analytics 8.2 on Viya 3.3, there are a number of new data features available. I’ll cover a few of these new features including the new data plan and data item features in SAS Visual Analytics in this blog.
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.
Often, in addition to content, an administrator will want to save configuration so that it can be reloaded or updated and applied to a different system. You have the ability to save and reload SAS Viya configuration using command-line interfaces. Learn more in this post.
SAS Visual Analytics takes advantage of the performance and scalability of the SAS Viya platform, providing a BI framework that can work with massive amounts of data, bringing forward the powerful analytics that has made SAS the market leader in this space. Learn more about SAS Visual Analytics on the new SAS platform.
Logs. They can be an administrator’s best friend or a thorn in their side. Thankfully, the chances of that happening with your SAS Viya 3.3 deployment is greatly reduced due to the automatic log management in SAS Viya, which archives log files every day.
For software users and SAS administrators, the question of how to streamline their approach into the easiest to use system that most effectively completes the task at hand. At SAS Global Forum 2018, the topic of a “Big Red Button” for the SAS Platform was an idea that got audience members excited. Here's a review of that talk.
You will not find an object in SAS Visual Analytics named Dynamic Text. Instead, you will find a Text object that allows you to insert dynamically driven data items. By using the Text object’s dynamic capabilities you can build custom report titles, object titles, emphasize measures and even supply the last modified time of the data source in your SAS Visual Analytics Report. In this post, I will outline the ways how you can leverage Dynamic Text in a SAS Visual Analytics Report.
Interactive reports with SAS Visual Analytics allow you to access the interface and product instantly. Simply choose a report to navigate and explore in our SAS Visual Analytics 8.2 viewer. There are reports for warranty analysis, retail insights, water consumption and quality, banking and risk and network performance.
It is imperative for developers, whether hardware or software engineers, to foresee unintended (probable or improbable) system usages and implement features that will make their creations foolproof, that is protected from misuse. Learn more about developing foolproof solutions with this old Russian anecdote.
SAS Enterprise Miner has been a leader in data mining and modeling for over 20 years. The system offers over 80 different nodes that help users analyze, score and model their data. Here are the Top Ten Tips for Enterprise Miner from a user with more than 20 years of experience.
SAS Viya is our latest extension of the SAS Platform and interoperable with SAS® 9.4. There were a number of SAS Viya presentations at SAS Global Forum 2018. In this series, we will review several of the most interesting talks. This post reviews Hadley Christoffels’ talk, A Need For Speed: Loading Data via the Cloud.
Learn how to change your working directory for SAS. Beginning with SAS® 9.4 TS1M4, you can use a new DATA step function, DLGCDIR, to change the location of your working directory.
The European Union’s General Data Protection Regulation (GDPR) taking effect on 25 May 2018 pertains not only to organizations located within the EU; it applies to all companies processing and holding the personal data of data subjects residing in the European Union, regardless of the company’s location. Here are four selected SAS tools for GDPR that allow you to protect personal data in SAS reports by suppressing counts in small demographic group reports.
The %SYSFUNC macro function allows you to access most SAS® functions. In this blog post, I demonstrate how %SYSFUNC can help in your programming needs when a macro function might not exist. I'll also share the formatting feature that is built in to %SYSFUNC and introduce the %QSYSFUNC that masks the returned value.
SAS Visual Analytics filters in 7.4 and 8.2 enable you to improve the appearance of reports based on calculations that use periodic operators. Parameter settings also enable you to provide users with a prompt for choosing the data to display in a report, without having any effect on the calculations themselves.
DESCENDING BY Variables in DATA Step Code that Runs Distributed in SAS Viya
At the Executive Conference at SAS Global Forum 2018 speaker Dan Heath says customer experiences are defined by peak moments. In this blog post, E.G. Nadhan, Chief Technology Strategist at Red Hat, shares his peak moments from SAS Global Forum 2018.
This post is an introduction to SAS Visual Forecasting 8.2. We'll build a Visual Forecasting (VF) Pipeline, which is a process flow diagram whose nodes represent tasks in the VF Process. The objective is to show how to perform the full analytics life cycle with large volumes of data: from accessing data and assigning variable roles accurately, to building forecasting models, to select a champion model and overriding the system generated forecast.
