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.
La Inteligencia Artificial (IA) y la analítica se han convertido en herramientas esenciales para las organizaciones que buscan mantenerse competitivas y relevantes en el mercado. La capacidad de analizar grandes volúmenes de datos y obtener información valiosa en tiempo real es ahora más importante que nunca. Acompáñenos en este blog
This article shows how to simulate data from a Poisson regression model, including how to account for an offset variable. If you are not familiar with how to run a Poisson regression in SAS, see the article "Poisson regression in SAS." A Poisson regression model is a specific type of
Fantasy sports are all about making the right calls—do you trust your gut, or do you trust the data? In fact, sports and data are a powerful combination and nowhere is that more evident than in the world of fantasy sports. Whether it's the excitement of the Premier League or
When using LLMs, managing toxicity, bias, and bad actors is critical for trustworthy outcomes. Let’s explore what organizations should be thinking about when addressing these important areas.
This article demonstrates how to use PROC GENMOD to perform a Poisson regression in SAS. There are different examples in the SAS documentation and in conference papers, but I chose this example because it uses two categorical explanatory variables. Therefore, the Poisson regression can be visualized by using a contingency
En el contexto de la responsabilidad fiscal de los ciudadanos, como lo estipula el artículo 31, fracción IV, de la Constitución Política de los Estados Unidos Mexicanos, es evidente que la evasión y las deducciones no justificadas siguen siendo un obstáculo importante para la recaudación de impuestos. Sin embargo, la
Who has time to be a nutritionist between work deadlines and swim practice? Not this working mom! But my tiny human needs her fuel, you know? This is why I’m thankful for nutrition labels. A quick scan at the grocery store tells me if that cereal is all sugar bombs
