Many well-known distributions become more and more "normal looking" for large values of a parameter. Famously, the binomial distribution, Binom(p, N), can be approximated by a normal distribution when N (the sample size) is large. Similarly, the Poisson(λ) distribution is well approximated by the normal distribution when λ is large.
SAS와 같은 글로벌 기업이 비즈니스를 할 때에는 글로벌 관점과 현지 관점의 균형을 맞추는 것이 중요합니다. 제품은 글로벌 시장 전반에 걸쳐 제공되어야 하고, 글로벌 경쟁력을 갖춰야 합니다. 반면, 고객과의 관계 구축은 현지 상황에 맞아야 합니다. 이는 적절한 현지 파트너와 협력을 통해서 강화할 수 있습니다. SAS코리아와 오랜 세월을 함께 동행해온 든든한 파트너,
As part of this year's IEEE Visual Analytics Science and Technology (VAST) Challenge, a group of SAS data scientists puit SAS Viya and related machine learning tools to the ultimate test - to identify individuals in a complex fishing network. Excitedly, the team received the Honorable Mention Award for Breadth of Investigation!
Foundation and domain models are transforming how businesses approach technology. These powerful tools are moving beyond the hype of GenAI, offering real solutions for a variety of tasks – whether generating text, creating visual content or even composing music. A new global survey of 1,600 organizations revealed critical insights into
Going forward, insurance will be based on data and AI – with a predict-and-prevent approach.
There are two programming tools that I rarely use: the SAS macro language and recursion. The SAS macro language is a tool that enables you to generate SAS statements. I rarely use the SAS macro language because the SAS IML language supports all the functionality required to write complex programs,
The SAS IML Language has a quirk with regards to functions that take no arguments. As discussed in the documentation, "modules with arguments are given a local symbol table." This is the usual behavior that programmers expect. However, the documentation goes on to state that "a module that has no

幼い頃、家の庭にたくさんのバラがあり、手入れが大変だった思いがある。トゲに刺されて痛い思いをしたり、傷になったりしたことを覚えている。興味深いことに、統計学の歴史にはナイチンゲールの「バラ」というグラフが登場する。 「白衣の天使」として知られるイギリスの看護師フロレンス・ナイチンゲールは、優れた統計学者でもあった。彼女は19世紀のクリミア戦争で看護師として派遣され、膨大な戦死者・傷病者データを分析し、多くの兵士が戦傷ではなく劣悪な衛生状態のために命を落としていることを明らかにした。その後、政治や行政に向けに「ローズダイアグラム」という革新的なグラフで報告した。 ローズダイアグラムは、円グラフの一種で、死因を視覚的に示すチャートである。月ごとの死亡者数を戦傷を赤、衛生状態や栄養不足を青、その他の要因を黒で色分けし、それぞれの面積で表現したものである（Florence Nightingale's Rose Diagram）。このグラフにより、衛生改善の必要性が明確になり、医療環境の改善が進んで傷病兵の死亡率が大幅に減少したのは言うまでもない。 統計学は記述統計と推測統計に分かれ、記述統計はデータの特徴を分かりやすく表現することを目的とする。ナイチンゲールの事例は、記述統計とデータ可視化が如何に重要かを物語っている。SASには「SAS Visual Analytics」という優れた可視化ツールがあり、基礎から上級までの関連コースも提供されている（SASトレーニングコース）。 2024年8月初旬 相吉
The foods that we choose to eat impact every aspect of our health, and as you can imagine, these food choices can also impact every aspect of an athlete’s performance. Choosing the right foods, at the right times, can improve power, strength, reaction time, endurance and recovery. Our young athletes
You’ve collected your data, organized it, and created a model to help you understand what you’re working with. Now what? For many organizations, the next step isn’t so clear. Only 50% of models ever make it to production, which means many aren’t even realizing the value of their investment. One
With a little preparation, a sense of humor, and a lot of deep breaths, you can successfully navigate this season. Here are some tips to help parents start the new school year! Get Your Supports in Place It’s time to create (or re-engage) your support system. Consider reaching out to
In SAS, the easiest way to draw random sampling from data is to use PROC SURVEYSELECT or the SAMPLE function in SAS IML software. I have previously written about how to implement four common sampling schemes by using PROC SURVEYSELECT and the SAMPLE function. The DATA step in SAS is
What sets the SAS Model Card apart from previous model cards is the use of descriptive visuals, to make model cards accessible to all personas involved in the analytics process, including data scientists, data engineers, MLOPs engineers, managers, executives, risk managers, business analytics, end-users, and any other stakeholder with access to the SAS Viya environment.
