If N random people are in a room, the classical birthday problem provides the probability that at least two people share a birthday. The birthday problem does not consider how many birthdays are in common. However, a generalization (sometimes called the Multiple-Birthday Problem) examines the distribution of the number of
In an earlier blog, I asked you to participate in CertMag/GoCertify’s Annual IT Salary survey. The response was fantastic and I’m happy to report that we made the list of the Top 75 IT certifications out of more than 900. This marks the first time SAS has been part of
Wenn ich mir die Zielbilder eigentlich aller Unternehmen in Bezug auf den Umgang mit ihren Kunden anschaue, so fällt immer dieselbe Aussage ins Auge: „Wir möchten den Kunden in den Mittelpunkt stellen und ihm ein positives Kundenerlebnis bieten“. SUPER! Das ist 1) nichts Neues und klingt 2) fast zu schön,
This article simulates the birthday-matching problem in SAS. The birthday-matching problem (also called the birthday problem or birthday paradox) answers the following question: "if there are N people in a room, what is the probability that at least two people share a birthday?" The birthday problem is famous because the
Forecasting Research Survey The Centre for Marketing Analytics and Forecasting at Lancaster University is conducting a new study on how demand forecasters do forecasting. They invite all practitioners who are working with forecasts, such as demand planners and supply managers, to take part in the study. The survey is anonymous
Can felons vote? This seemed like a simple question, but I realized that I wasn't 100% sure of the answer. Therefore I looked into the data ... and apparently "it depends". Follow along and see how I created a map to help answer this question. But before we take the
This is a guest blog by Shelly Hummel, LMFT and Carole Cullen, LMFT as part of the Work/Life February Relationships Series. We offer our sincere thanks to Shelley and Carole for volunteering to contribute! Jennifer and Dave have been married for 3 years. “We have a huge argument every December
Wahrscheinlich schreibt Richard David Precht gerade an einem Buch über künstliche Intelligenz – und es wäre wirklich nicht schlecht, wenn sich möglichst viele Menschen so genau wie möglich über dieses Thema informieren könnten, ohne selbst Spezialist sein zu müssen. Denn, das ist 2017 bereits klar geworden, künstliche Intelligenz betrifft uns
For the past few years, I've been hearing from many news sources that Detroit is the most violent large city in the US. If the news is saying this, then the data should corroborate it, eh? Well, of course I decided to check for myself... When comparing crime data across
Do you know what the #1 fear in North America is? Most people say fear of public speaking or fear of death, but you may just want to consider this new fear upping the charts - the fear of writing a SAS Certification exam! The real test begins before even
@philsimon provides more thoughts about the opportunity that GDPR provides marketing departments.
As a former intelligence analyst, I can't help but breathe a huge sigh of frustration. The special AI "task forces" and their massive budgets are great, but it's time to get honest about the rest of the military. Ask any every day soldier, sailor, airman or Marine their opinion of
Kundenerfahrungen in Echtzeit genießen einerseits hohe Priorität in Marketingabteilungen vieler Unternehmen, die Umsetzung ist andererseits vielfach noch eine Herausforderung. Da der Marktdruck durch das Internet und die Digitalisierung immer größer wird, sind die Unternehmen gezwungen, ihren (potenziellen und realen) Kunden ein Erlebnis während der Interaktion oder im Dialog zu vermitteln,
This article shows how to construct a "stacked band plot" in SAS, as shown to the right. (Click to enlarge.) You are probably familiar with a stacked bar chart in which the cumulative amount of some quantity is displayed by stacking the contributions of several groups. A canonical example is
Can you use a data visualization tool to display building maps, floor designs and other Esri data? With the recent addition of custom polygon support in SAS Visual Analytics 8.2, customers wondered if this feature can be utilized to render different types of regional overlays. A common request is to
The flu seems to be especially potent this year. "How potent is it," you might ask? ... Well, let's plot some data on a map to help find out! Here in the US, the Centers for Disease Control and Prevention (CDC) compiles data about diseases, and provides reports and graphs
금융감독원에 따르면 2017년 상반기 적발된 보험 사기 금액은 전년 동기 대비 6.4% 증가한 3,703억원으로 역대 최고치를 기록했습니다. 또한 보험연구원은 2014년 기준 보험 사기로 인한 누수 금액이 무려 4조5,000억원에 달하는 것으로 발표했는데요. 특히 전문 브로커가 연루되는 등 사기 수법 또한 지능적, 조직적으로 진화함에 따라 보다 체계적인 조사 방식과 분석 시스템의 필요성이 높아지고
Have you, or someone you know, gotten the flu this year? Word on the street is that this year's flu might be particularly bad, and the data seem to be corroborating that so far. You don't want to take my word for it? -- well then, let's have a look
I ran across an interesting conundrum the other day. The intent was to compare the value of X to a list of desired values, and if X matched one of the values in the list, set Flag to 1, otherwise set Flag to 0. I wrote and executed this test program,
Enochlophobia. It means “fear of crowds,” and I have it. I wouldn’t be caught dead anywhere near Times Square on New Years’ Eve, and how did I ever endure the stadium-sized rock concerts of my youth? I’m thinking all this as I navigate the sea of people at the National
What is a random number generator? What are the random-number generators in SAS, and how can you use them to generate random numbers from probability distributions? In SAS 9.4M5, you can use the STREAMINIT function to select from eight random-number generators (RNGs), including five new RNGs. After choosing an RNG,
SAS University Edition や SAS OnDemand for Academics は、教育・研究・学習目的に無償で使えるソフトウェアですが、使い方の学習には教材が必要だという方もおられると思います。もちろん、SASはソフトウェアに関する膨大なドキュメントをご用意していますが、「どこから始めたらいいの？」「英語ではちょっと…」という声もあるでしょう。 SAS Japanでは、SAS入門者の方向けに日本語字幕をつけたチュートリアル・ビデオ群をご用意しています。このビデオは、ほとんどが5～10分の短いもので、SASとは何かから始まり、SAS University Edition や SAS OnDemand for Academics のインターフェイスである SAS Studio の解説、他の環境との差、データへのアクセス、データの操作、グラフの作成、基本的な統計解析、時系列分析の手法をサンプルデータを使いながら説明しています。サンプルデータは、標準でSASに付属しているものや、オンラインドキュメントを参考にして作成するものなどがあり、どなたでも、どんな環境でも学習を開始することができます。 これらの SAS Studio の使用法の解説では、主に「タスク」とよばれる機能を用いた操作を行います。「タスク」は、「棒グラフの描画」や「分散分析」などの機能をプログラミングなしで利用するためのインターフェイスで、データやパラメータをマウス等で指定することで、SASのプログラム・コードが自動生成されます。もちろん、SASの機能を最大限引き出すために、ゼロからプログラムを書くことも可能です。自動生成されたプログラムを参考にしながら、SASプログラミングを学習することにも適しています。 実は、これらの日本語字幕付きのビデオは、SASのチュートリアル・ビデオのごく一部で、SAS Video Portal にはより多くのビデオが用意されています。ここでは、SAS製品の紹介や、操作法・プログラミングのチュートリアルに加え、SASのアナリティクスが実際の活用事例を紹介する Analytics in Action ビデオもご覧になれます。音声は英語のみですが、英語や日本語の字幕を表示できるものもあります。まずはビデオから、SASアナリティクスの世界を覗いてみませんか？
前回、SAS OnDemand for Academics (SODA) の Course 機能を活用することで、授業準備の手間が軽減されることをご紹介しましたが、実は、Cource 登録にはもう一つのメリットがあります。 SODA は、SAS Studioを基本のインターフェイスとしていますが、Course 登録により使用できる製品が増えます。 SAS Enterprise Guide : ポイント&クリック操作によるWindowsアプリケーション SAS Enterprise Miner : GUIによるデータマイニング・ツール SAS Forecast Server : 時系列予測の自動作成ツール これらは、統計の学習よりも、実際のビジネス等の現場で素早く統計手法を適用するためのツールで、基礎を学習した上で、より応用に際して活用できるものです。
Let’s lay down some fundamentals. In business you want to achieve the highest revenues with the best margins and the lowest costs. More specifically, in manufacturing, you want your products to be the highest quality (relative to specification) when you make the item. And you want it shipped to the
A chatbot is a computer program that uses natural language processing (NLP) and artificial intelligence to simulate human conversation and derive a response. Essentially, it’s a machine that can chat with you or respond to your chatter. Chatbots can save time and money when used to handle simple, automated tasks.
The 38th International Symposium on Forecasting will be held June 17-20 in Boulder, Colorado, USA. Registration is now open. This is the last ISF in North America until at least 2022. The ISF is the premier forecasting event for researchers, with academic attendees from all over the world. Yet it
Data doesn't always have to be 'big data' to be interesting. For example, I recently ran across a small, but very interesting, database containing all of North Korea's missile tests. The data was a bit difficult to digest in the formats provided, therefore I decided to try my hand at
자율주행차, 커넥티드 기기, 디지털 트랜스포메이션, 사물인터넷(IoT), 머신러닝, 인공지능(AI), 자동화 등 2017년 한 해를 주도해온 기술 트렌드는 2018년은 물론 그 미래에까지도 계속될 것입니다. 실질적인 차이는 이 기술들의 결합에서 찾을 수 있는데요. 한 예로, 인공지능과 사물인터넷은 그 자체로 트랜스포메이션의 성격(transformative)을 지닙니다. 사물인공지능(artificial intelligence of things)으로 구현될 연결되고 자동화된 세상의 디지털 트랜스포메이션을 상상해보세요. 2018년에는 지능(intelligence)과
David Loshin says the hardest part of compliance is knowing if a data asset contains personal data, and ensuring you can protect it.
A popular way to use lists in the SAS/IML language is to pack together several related matrices into a single data structure that can be passed to a function. Imagine that you have written an algorithm that requires a dozen different parameters. Historically, you would have to pass those parameters
