Create an ogive in SAS

My son is taking an AP Statistics course in high school this year. AP Statistics is one of the fastest-growing AP courses, so I welcome the chance to see topics and techniques in the course. Last week I was pleased to see that they teach data exploration techniques, such as

Simulate data from a generalized Gaussian distribution

Although statisticians often assume normally distributed errors, there are important processes for which the error distribution has a heavy tail. A well-known heavy-tailed distribution is the t distribution, but the t distribution is unsuitable for some applications because it does not have finite moments (means, variance,...) for small parameter values.

Christoph Keese: Silicon Valley

Die Springer-WG im Silicon Valley wurde zunächst belächelt und beargwöhnt. Hat es das schon einmal gegeben? Ein deutscher Konzern schickt eine Handvoll seiner Top-Manager für einen längeren Aufenthalt in eine andere Weltgegend mit dem Auftrag, die Geschäftsmodelle der Zukunft zu sondieren. Herausgekommen sind ikonisch gewordene Bilder eines Vollbart tragenden Kai

The distribution of nearest neighbor distances

Last week I showed how to compute nearest-neighbor distances for a set of numerical observations. Nearest-neighbor distances are used in many statistical computations, including the analysis of spatial point patterns. This article describes how the distribution of nearest-neighbor distances can help you determine whether spatial data are uniformly distributed or

Verbündete gegen steigende Gesundheitskosten

Deutschland ist beliebt bei Auswanderern. Was von Menschen aus anderen Ländern, die hier wohnen und arbeiten, positiv hervorgehoben wird, ist laut einem aktuellen Report unter anderem die Gesundheitsversorgung. Und diese Qualität hat ihren Preis. Die Pro-Kopf-Ausgaben im Gesundheitswesen steigen mehr oder weniger seit Jahren kontinuierlich. Doch gibt es Verbündete gegen

Nine years (and still together)

The IT industry is littered with examples of short-lived corporate partnerships and alliances that often appear impressive but regularly end or are withdrawn after the initial enthusiasm wanes. The old adage that “actions speaker louder than words” is especially pertinent and I regularly encourage clients to look for tangible examples

Overlay a curve on a bar chart in SAS

One of the strengths of the SGPLOT procedure in SAS is the ease with which you can overlay multiple plots on the same graph. For example, you can easily combine the SCATTER and SERIES statements to add a curve to a scatter plot. However, if you try to overlay incompatible

From compliance to commitment: The power of student growth data

As teachers, we lean into our experience. We trust our judgment about students and our instruction. We trade teaching stories with colleagues. And increasingly, we examine student growth data that illuminates our practice and occasionally suggests we refine our approach to individual students. In the past decade, states and districts
