Use a heat map to visualize an ordinal response in longitudinal data

Recently, I showed how to use a heat map to visualize measurements over time for a set of patients in a longitudinal study. The visualization is sometimes called a lasagna plot because it presents an alternative to the usual spaghetti plot. A reader asked whether a similar visualization can be

Successful citizen data scientists need to know these three trends

Data visualization is a critical way for anyone to turn endless rows of data into easy-to-understand results through dynamic and understandable visuals. Whether your favorite visualization is a pie chart, a geographic map or relies on natural language, showing the insights that empower you to make more informed decisions is a better way to do data-driven business. Analyst firms say that SAS has market-leading data visualization. This helps users across the globe find insights in their data using new and exciting trends in data visualization.

The Beatty sequence for pi

Did you know that you can use π to partition the positive integers into two disjoint groups? It's not hard. One group is generated by the integer portions of multiples of π. The FLOOR function gives the integer portion of a positive number, so you can write integer that are

SASのオンライン学習コース「Skill Builder for Students」の紹介（３）Visual Analytics and Visual Statistics編

前回の記事では、学生であれば無料で利用可能なオンライン学習コース「Skill Builder for Students」のProgrammingコースについての概要を紹介しました。今回は引き続きまして、Visual Analytics and Visual Statisticsコースについて紹介していきます。データアナリティクスへの興味・関心は近年急激に増加しています。ただ特に学習を始めた学生では、データアナリティクスと聞くと、どうしても複雑なモデルを組むことや機械学習を実施することだけに意識が向いている印象を受けます。しかしデータアナリティクスの本質はそこではありません。根幹にあるのは意思決定や業績の改善にどれほど貢献できるかです。データの可視化、見える化は学生ですとしばしば軽視されがちな部分ではありますが、意思決定や現状の把握においては非常に有用な有用な方法の一つです。今回紹介するコースではSAS Viyaプラットフォーム上でSAS Visual AnalyticsとSAS Visual Statisticsを使用し、様々な可視化方法、予測モデルについて学習を行います。これらを学習することによってデータに潜む傾向やパターンを把握し、そしていかにその後のリスク管理や傾向の予測などへとつなげていくかといった実践的なデータアナリティクスを学ぶことが可能です。またSAS ViyaはSASによるプログラミング以外にもRやPythonといった他のプログラミング言語をサポートしているため、SASのコーディングができない方であっても不自由なく利用することが可能となっています。 Visual Analytics and Visual Statisticsコースへのアクセスは以下の手順です。 Skill Builder for Studentsへログイン「Learn SAS」というタブをクリック画面中央の「Start Learning」をクリック「Visual Analytics and Visual Statistics」をクリック展開される各種e-learningコースをクリック画面下部にある「enroll」をクリック Visual Analytics and Visual Statisticsコースの概要本コースは SAS Visual Analytics 1 for SAS

Is it really better to give than to receive? Data science says yes

Active gratitude is the feeling you get when a stranger does something nice for you without expecting anything in return. While both are beneficial for our health, there is a statistically significant, positive correlation between active gratitude and pro-sociality (r = 0.374), that is not present with passive gratitude. In other words, random acts of kindness trigger other random acts of kindness to other people, which is both good for us and good for society.
