The length of the string of lights that you need to wrap around your Christmas tree
Christmas whimsy or practical advice? You decide! Rick Wicklin asks and answers the age-old question, "How many Christmas tree lights do you need for your tree?" Using geometry and a SAS program, you can evaluate mathematical formulas for estimating the length of a string of lights for placing lights on a perfectly conical evergreen.

SAS Viya Copilot | SAS Viya October and November Release
This month's SAS Viya Release Highlights Show features the launch of Code Assistance and Model Development capabilities in SAS Viya Copilot, in addition to an overview of Model Context Protocol. We will also be covering updates from the latest SAS Viya releases (10.2025 and 11.2025), including SAS Settings in Microsoft 365, Specific Python Version, and Compare Data Step in SAS Studio.

Getting Started with Job Scheduling in SAS Viya
SAS Viya makes automating your analytics easy. Instead of manually triggering jobs, you can schedule programs, data loads, and reports to run at specific times or on recurring intervals. This article walks through creating a job in SAS Studio and using Environment Manager to set triggers, manage schedules, and streamline workflows, so your processes run reliably without constant oversight.

The afterparty: Hyperparameter autotuning revisited
Hyperparameter tuning just got easier in SAS Viya Workbench. With a single line in PROC GRADBOOST, you can enable autotuning to optimize model performance automatically, saving time and improving accuracy without manual trial and error.

TouchDuck! Exploring unique features of SAS/ACCESS to DuckDB through college football
Discover how SAS/ACCESS to DuckDB simplifies data exploration. Using college football data as an example, the article highlights DuckDB’s flexibility and integration with SAS Viya for efficient queries and transformations, ideal for lightweight, in-process analytics without heavy infrastructure.

SAS Viya: Powering smarter decisions at lower cost and in shorter time
SAS Viya helps you make smarter decisions faster and at lower cost. By leveraging options like APPLYROWORDER with LOGSELECT and GENSELECT procedures, you can streamline repeated measures analyses, saving time and resources while improving efficiency in complex modeling tasks.

Mapping data over images
Learn how to overlay data on custom images in SAS Viya using ArcGIS tools. This step-by-step guide shows how to geo-reference any image (like a stadium photo) and integrate it into SAS Visual Analytics for fully customizable mapping and interactive reports.

Validating your Values with the Compare Data Step
Quickly validate your data with SAS Studio’s Compare Data step. This point-and-click feature lets you compare variables across datasets or within the same dataset, choose comparison methods (Absolute, Exact, Percent, Relative), and generate output tables for deeper analysis.

Leveraging Database Indexes to Improve Performance
Indexes can dramatically boost query performance in SAS when working with large datasets. Learn how creating simple or composite indexes, whether in SAS or on database tables accessed via SAS/ACCESS, can make filtering, joins, and BY-group processing up to 106× faster, with practical examples and validation steps.

The rise of small language models for information extraction
Small language models are gaining traction for efficient, auditable information extraction. Unlike large LLMs, these lightweight models (such as GLiNER for named entity recognition) offer lower cost and greater transparency while outperforming traditional rule-based approaches in structured data tasks.

Strategic fundraising powers more breakthroughs in childhood cancer research
The Kids’ Cancer Project is using SAS Customer Intelligence 360 and Managed Cloud Services to transform donor engagement and boost fundraising for childhood cancer research. This data-driven approach has helped the charity achieve a 19.9% increase in regular giving and gain real-time insights into donor behavior, fueling its mission to improve survival rates and quality of life for young patients.

Introducing the SAS Agentic AI Accelerator: Build AI Agents Seamlessly in SAS Viya
In this article, Marinela Profi introduces you to SAS Agentic AI Accelerator. Many of us are exploring how to use Large Language Models (LLMs) for more than just simple chat. The logical next step is building systems that can perform multi-step tasks - often called AI agents - systems that go beyond basic chat and can perform multi-step tasks, orchestrate workflows, and drive decisions. However, integrating these complex systems into existing enterprise environments — while ensuring governance, scalability, and security — can be a real challenge.
