Two of my colleagues have shared their experiences as a statistic and a child who could have been left behind. I too have my own story that helped drive my passion. All of us define equity in different ways. Equity is a concept that is hard to define, and we
For colleges and universities, awarding financial aid today requires sophisticated analysis. When higher education leaders ask, “How can we use financial aid to help meet our institutional goals?” they need to consider many scenarios to balance strategic enrollment goals, student need, and institutional finances in order to optimize yield and
Lengthens inner thigh and side waist. Engages core and lengthens spine while opening chest, arms and shoulders. Gate Pose (Sanskrit: Parighasana) Begin on mat kneeling with toes curled under and torso lengthened with crown reaching tall. Extend your right leg out to the right and press your entire foot into
As many of the regular readers of this blog know, SGPLOT and GTL, provide extensive tools to build complex graphs by layering plot statements together. These plots work with axes, legends and attribute maps to create graphs that can scale easily to different data. There are, however, many instances where
In an IoT world, everything is connected. But what does it mean to be connected? Does it mean being plugged in to your phone, car, home, TV, favorite apps and retailers? Does it mean knowing what’s happening all around you? And having the “things” you’re connected to acting as recommender
When building models, data scientists and statisticians often talk about penalty, regularization and shrinkage. What do these terms mean and why are they important? According to Wikipedia, regularization "refers to a process of introducing additional information in order to solve an ill-posed problem or to prevent overfitting. This information usually
Los usuarios empresariales dependen de la disponibilidad de los datos, que estos sean confiables y que estén fácilmente disponibles cuando se necesita. Sin embargo, con datos dispersos en sistemas dispares y volúmenes de datos que aumentan rápidamente, la integración de estos no es una tarea fácil. Ante tal escenario,
Is this menopause? Maybe you've noticed some changes. Perhaps it’s the occasional hot flushed feeling that erupts like a volcano or maybe it's the irregular periods when you’ve always been like clockwork. Although menopause is often thought of as a singular event, it isn’t unless you are undergoing chemotherapy that
Helmut Plinke explains why modernizing your data management is essential to supporting your analytics platform.
A SAS customer asked how to use SAS to conduct a Z test for the equality of two proportions. He was directed to the SAS Usage Note "Testing the equality of two or more proportions from independent samples." The note says to "specify the CHISQ option in the TABLES statement
최근 금융, 통신, 자동차, 공공, 리테일, 교육 등 모든 산업을 관통하고 있는 한 단어가 있습니다. 바로 4차 산업혁명인데요. 빅데이터, 사물인터넷(IoT), 인공지능(머신러닝), 로봇 등 첨단 ICT 기술의 융합으로 완성되는 4차 산업혁명은 미래 산업의 필수 성장 동력으로 자리잡았습니다. 그 중에서도 특히 제조업은 이른바 ‘인더스트리 4.0’의 촉발과 함께 그 새로운 혁명의 시작을 알렸는데요.
Tomorrow is Independence Day, a federal holiday in the United States. Flags are displayed everywhere, especially in Washington, D.C., where I live. So let's have a little Fun with Flags! The current U.S. flag has 50 stars, one per state, with five rows of six stars interleaved with four rows
When I arrived for a training course with the name, "Powerful storytelling for tech," I was surprised to discover that most of the attendees worked in sales, rather than the marketing and communications crowd I'd been expecting. They were all there to learn how best to engage prospects – how
みなさま、こんにちは。 さて突然ですが、フーリエ変換ってご存知ですか？ おそらく物理学や経済学で波形データを分析したことのある方には馴染みがあるでしょうが、フーリエ変換は波形データを扱う手法です。 フーリエ変換では周期的な波形を、sin波やcos波の重ね合わせで説明しようというものです。 たとえば以下のような波形データは、どの時間にどのくらいの強さの波が流れているかを表現しています。 これをフーリエ変換することで、周波数と振幅で表すことができるようになります。 ↓ フーリエ変換！ ↓ 従来のSAS製品では波形データでフーリエ変換をする機能を提供していなかったのですが、SAS ViyaのSAS Forcastingという製品を使うことで、フーリエ変換を実施することができるようになりました。 SAS Viyaでできるのは短時間フーリエ変換（Short time Fourier transform）です。 今回はSAS Viyaでフーリエ変換を実施してみたいと思います。プログラミング言語はPythonを使用します。 まずは前準備として、必要なライブラリをインポートし、CAS sessionを作成します。 CAS sessionはSAS Viyaでデータ分析を行うCASというエンジンへ認証し、接続するものです。 # CAS sessionの用意 import swat host = "localhost" port = 5570 user = "user" password = "p@ssw0rd" mysession = swat.CAS(host, port, user, password) #
If you spend a lot of time in SAS Enterprise Guide (as I do), you probably get to know its features pretty well. But we don't always take the time to explore as we should, so there might be a few golden nuggets of editor knowledge that have escaped you
