SAS' Federica Citterio answers the perennial data science question: "How can I trust (generative) LLM to provide a reliable, non-hallucinated result?"
A SAS programmer wanted to estimate a proportion and a confidence interval (CI), but didn't know which SAS procedure to call. He knows a formula for the CI from an elementary statistics textbook. If x is the observed count of events in a random sample of size n, then the
In a recent article, I graphed the PDF of a few Beta distributions that had a variety of skewness and kurtosis values. I thought that I had chosen the parameter values to represent a wide variety of Beta shapes. However, I was surprised to see that the distributions were all
Thanks to the ubiquity of smartphones and laptops, people are used to getting what they need at the press of a button – whether they’re looking for information, seeking action or trying to solve a problem. Citizens want that same ease of access from their city’s government. As more citizens
The moment-ratio diagram is a tool that is useful when choosing a distribution that models a sample of univariate data. As I show in my book (Simulating Data with SAS, Wicklin, 2013), you first plot the skewness and kurtosis of the sample on the moment-ratio diagram to see what common
In a world where MarTech complexity is skyrocketing, utilization has declined sharply and the integration of data and technology are a marketer’s biggest tech challenges, CMOs are under pressure to prove marketing ROI. However, the combination of SAS and the Snowflake Data Cloud presents a value proposition that is hard
A SAS programmer wanted to simulate samples from a family of Beta(a,b) distributions for a simulation study. (Recall that a Beta random variable is bounded with values in the range [0,1].) She wanted to choose the parameters such that the skewness and kurtosis of the distributions varied over range of
A dot plot is a standard statistical graphic that displays a statistic (often a mean) and the uncertainty of the statistic for one or more groups. Statisticians and data scientists use it in the analysis of group data. In late 2023, I started noticing headlines about "dot plots" in the
Authors: Steven Harenberg and Amy Becker The total solar eclipse taking place across a thin band of the United States on April 8, 2024, is going to be a stellar event. In this post, we will help plan a journey to see the total solar eclipse. We will use algorithms
SAS Viya can allow users and organizations to more easily interface with the LLM application, build better prompts and evaluate systematically which of these prompts leads to the best responses to ensure the best outcomes.
My colleague Rick Wicklin maintains a nifty chart that shows the timeline of SAS releases since Version 8. A few of you asked if I could post a similar chart for SAS Enterprise Guide. Here it is. Like Rick, I used new features in SAS 9.4 to produce this chart
SAS' Varun Valsaraj demonstrates how to build a digital assistant for a warehouse space optimization use case.
Recently, I saw a scatter plot that displayed the ticks, values, and labels for a vertical axis on the right side of a graph. In the SGPLOT procedure in SAS, you can use the Y2AXIS option to move an axis on the right side of a graph. Similarly, you can
Adopting analytics and AI in the public sector is changing how governments make decisions. Technology improves the efficiency and transparency of work processes, positively impacting service delivery to increasingly demanding citizens. However, many government organizations still need help fully embracing a data-driven culture. The Covid-19 pandemic is one of the
A recent article describes how to estimate coefficients in a simple linear regression model by using maximum likelihood estimation (MLE). One of the nice properties of an MLE formulation is that you can compare a large model with a nested submodel in a natural way. For example, if you can
SAS announces continued support and releases for SAS 9 and a new role for SAS Enterprise Guide with SAS Viya.
Concerns about risk and the fear of change can be some of the biggest barriers to career development. Following the release of her book Leap: Why It’s Time to Let Go To Get Ahead in Your Career, author Jessica Galica invites you to reframe your view on risk. Speaking for
1. ‘SAS 컨테이너 런타임’이란? SAS는 SAS Viya 2021.1.1.3에서 SAS 컨테이너 런타임(SAS Container Runtime, 이하 SCR)을 출시했으며, 그 이후 많은 고객이 운영환경에서 SCR을 구현했습니다. 이 혁신적인 런타임 엔진은 SAS 모델과 의사결정을 Open Container Initiative (OCI) 호환 컨테이너에 배포하는 역할을 합니다. SCR은 표준 기술을 사용하여 SAS Viya 외부에서 모델과 의사결정을 실행합니다. 클라우드
A statistical analyst used the GENMOD procedure in SAS to fit a linear regression model. He noticed that the table of parameter estimates has an extra row (labeled "Scale") that is not a regression coefficient. The "scale parameter" is not part of the parameter estimates table produced by PROC REG
SAS' Julia Florou-Moreno shows you how to use generative AI to build a digital assistant that interacts with a model using natural language conversation.
Happy Pi Day! Every year on March 14th (written 3/14 in the US), people in the mathematical sciences celebrate all things pi-related because 3.14 is the three-decimal approximation to π ≈ 3.14159265358979.... Pi is a mathematical constant defined as the ratio of a circle's circumference (C) to its diameter (D).
Making a difference involves taking meaningful actions that contribute positively to society. Whether it's through volunteering, creating innovative solutions or advocating for important causes, each action advances change. This is the third post in a new series highlighting women from diverse backgrounds as they share their experiences in the tech
I recently wrote about the Number-Word Game, which is an iterative algorithm that generates a sequence of natural numbers by using the lengths of the words for the numbers. In English, the words are "one", "two", "three", and so on. You can play the Number-Word Game in any alphabetic language
Have you heard about the Number-Word Game? This is a simple game that has the following rules: Start with any positive integer. Write down the English word for the integer. Count the number of letters in the word. This gives a new positive integer. Go to (2). Repeat until a
I sometimes see analysts overuse colors in statistical graphics. My rule of thumb is that you do not need to use color to represent a variable that is already represented in a graph. For example, it is redundant to use a continuous color ramp to represent the lengths of bars
This phenomenon has been in the news recently, so I've updated this article that I originally published in 2017. The paper currency in circulation in the US is mostly $100 bills. And not just by a little bit -- these account for 34% of the notes by denomination and nearly

With four parameters I can fit an elephant. With five I can make his trunk wiggle. — John von Neumann Ever since the dawn of statistics, researchers have searched for the Holy Grail of statistical modeling. Namely, a flexible distribution that can model any continuous univariate data. As the quote
After reading about the tragic attack and death of Nex Benedict, a 16 year old non-binary student in Oklahoma, I sat down to write another blog post about why we need to take care of our gender diverse community and how to support our gender diverse teens at a time
