According to Hyndman and Fan ("Sample Quantiles in Statistical Packages," TAS, 1996), there are nine definitions of sample quantiles that commonly appear in statistical software packages. Hyndman and Fan identify three definitions that are based on rounding and six methods that are based on linear interpolation. This blog post shows
고객관계관리(CRM), 여행 산업의 핵심 경쟁력으로 떠올라 요즘 ‘먹방’과 ‘쿡방’의 인기를 무섭게 따라잡고 있는 트렌드가 있습니다. 바로 ‘여행 방송’입니다! 꽃보다 할배의 열풍을 시작으로 원나잇 푸드트립, 패키지로 세계 일주 – 뭉쳐야 뜬다, 배틀 트립 등 각종 여행 방송이 쏟아지고 있는데요. 실제 방송 후 관련 여행 상품들의 매출이 증가하면서 그 인기를 증명하고 있죠!
These days, more and more people move to where the work is. And for many people in Europe, that 'where' is Germany. I recently saw a map of Germany, that showed which country had the most foreigners living in each area. It was an interesting map, but I thought I might
Ich möchte Sie etwas fragen? Sehen Sie Risikomanagement als: alleinige Aufgabe des Chief Risk Officer, als Pflichtübung, die jede Menge Papierkram – aber keine wirklichen Vorteile – bringt; oder Verantwortung von allen im Unternehmen und eine Chance, eine sichere Umgebung für heikle Geschäftsentscheidungen zu schaffen? Natürlich sind diese beiden Auffassungen

In last week's article about the Flint water crisis, I computed the 90th percentile of a small data set. Although I didn't mention it, the value that I reported is different from the the 90th percentile that is reported in Significance magazine. That is not unusual. The data only had
My colleague Gerhard Svolba (Solutions Architect at SAS Austria) has authored his third book, Applying Data Science: Business Case Studies Using SAS®." While the book covers a broad range of data science topics, forecasters will be particularly interested in two lengthy case studies on "Explaining Forecast Errors and Deviations" and
오탐(False Positive), 자금세탁방지(AML)의 새로운 도전 과제 2016년 2월, 미국 재무부 산하의 금융범죄단속반 ‘FinCEN(Financial Crime Enforcement Network)’은 플로리다 주 지브롤터 프라이빗 뱅크(Gibraltar Private Bank)와 트러스트 컴퍼니(Trust Company)에 자금세탁방지(AML: Anti-Money Laundering) 프로그램의 ‘상당한’ 결함을 이유로 4백만 달러의 벌금을 부과했습니다. 글로벌 금융 업계의 이목은 당시 보고된 여러 결함 중 ‘오탐(false positives)’으로 쏠렸습니다. *오탐(False Positive): 잘못
In recent years, solar panels have become much more economical, and therefore more popular. But because of the curvature of the Earth, the angle at which you need to install the panels varies, depending on where you live. In this example, I demonstrate how to visualize this kind of data
David Loshin explores considerations for organizations gradually making the transition to Hadoop.
Conversations around equity in education are at a fever pitch. Decades of research show that students of color and low-income students are disproportionately taught by less effective or more inexperienced teachers. Civil rights leaders encouraged the Obama administration to require states to develop Equity Plans to ensure that every student
Ensemble methods are commonly used to boost predictive accuracy by combining the predictions of multiple machine learning models. The traditional wisdom has been to combine so-called “weak” learners. However, a more modern approach is to create an ensemble of a well-chosen collection of strong yet diverse models. Building powerful ensemble models
Are you caught up in the machine learning forecasting frenzy? Is it reality or more hype? There's been a lot of hype about using machine learning for forecasting. And rightfully so, given the advancements in data collection, storage, and processing along with technology improvements, such as super computers and more powerful
The US unemployment rate was down to 4.4% in April, which is the lowest we've seen since before the big recession (about 10 years ago). But a single number seldom tells the whole story, so let's look at unemployment data in several different ways, to get a more complete picture...
Wirtschaftskriminelle Handlungen zu entdecken und zu verhindern, ist ein kontinuierlicher Prozess, dessen Optimierung der Versicherung finanzielle Vorteile verschafft und Reputationsschäden verhindert. Eine entscheidende Rolle spielen dabei vor allem die Prävention und eine optimierte Identifikation von Betrugsversuchen durch fortgeschrittene analytische Verfahren. Die meisten der im Betrug durch Vermittler anzutreffenden Handlungen manifestieren
Der Interpretationsspielraum zwischen „Bean Counter“ und „Business Partner“ ist immens. Nicht umsonst sind die Meinungen sehr unterschiedlich, welcher konzeptionelle Controlling-Ansatz der „richtige“ ist. Nicht nur in der Wissenschaft, sondern auch in der Praxis findet man deutliche Unterschiede vor, welches Selbstverständnis das Controlling in den Unternehmen hat. Ich möchte heute jedoch
The April 2017 issue of Significance magazine features a cover story by Robert Langkjaer-Bain about the Flint (Michigan) water crisis. For those who don't know, the Flint water crisis started in 2014 when the impoverished city began using the Flint River as a source of city water. The water was
Deep learning made the headlines when the UK’s AlphaGo team beat Lee Sedol, holder of 18 international titles, in the Go board game. Go is more complex than other games, such as Chess, where machines have previously crushed famous players. The number of potential moves explodes exponentially so it wasn’t
Phil Simon looks at AWS's evolution before making some predictions about the future of Hadoop.
빅데이터 시대의 데이터 사이언티스트를 향한 도전! SAS코리아가 ‘제 15회 SAS 분석 챔피언십’을 개최합니다. SAS 분석 챔피언십은 차세대 데이터 사이언티스트를 양성하고 그 저변을 확대하기 위해 기획된 공모전입니다. 지난 2002년 제 1회를 시작으로 국내 가장 오랜 전통과 전문성을 자랑하는 빅데이터 공모전으로 자리잡았습니다. LG유플러스의 후원으로 진행되는 올해 SAS 분석 챔피언십의 분석 과제는 ‘나도 몰랐던 나의 취향을
Artificial intelligence. Big data. Cognitive computing. These buzzwords are the ABCs of today’s marketplace. In a recent interview at SAS® Global Forum, I discussed the unprecedented pace of change that we’re seeing in the market. It’s creating what I like to call an analytics economy. In this economy, analytics –
Es hat eine lange Tradition, teilweise freiwillig, teilweise aus der Not geboren: Dinge selbst in die Hand zu nehmen. „Do-it-yourself – Selbst ist der Mann/die Frau – wenn-du-willst-das-etwas-erledigt-wird-dann-mach-es-selbst“. Oder halt IKEA-Möbel, Brotbackautomaten beim Discounter, BI-as-a-self-Service, Online-Banking … Mit der Kommentarfunktion dürfen Sie später die Liste gerne ergänzen! Und das hat
The forecast is frightening: Robots will take over all manual labor and self-generating code will automatically spin out the algorithms once developed by statisticians and programmers. Humans will become obsolete. What will mere mortals do all day long? Ride captive as our self-driving cars take us on a sentimental journey
I guess a coding dinosaur is someone who uses an old/legacy computer language, or at least a language that isn't en vogue these days. Coding dinosaurs are still around (and probably will be for a while), whereas the real dinosaurs that lived millions of years ago are extinct. What caused
The little SAS program’s official name was Extract_Transform_Load_ 0314.sas. But, that name was much too formal, way too long, and did not roll off of the tongue very easily at all. So, everybody simply called her: ETL Pi. ETL Pi was conceived in a 2-hour project strategy meeting in conference
