Avoiding the digital transformation technology trap

In a world increasingly characterized by digital economies and disruption, every market disturbance exponentially widens the business agility gap between the less digitally evolved and those companies that have demonstrated innovation leadership through digital transformation. For those that are not transforming with urgency, the negative consequences will become compounded to

Estimate a bivariate CDF in SAS

This article shows how to estimate and visualize a two-dimensional cumulative distribution function (CDF) in SAS. SAS has built-in support for this computation. Although the bivariate CDF is not used as much as the univariate CDF, the bivariate version is still a useful tool in understanding the probable values of

The probability integral transform

This article uses simulation to demonstrate the fact that any continuous distribution can be transformed into the uniform distribution on (0,1). The function that performs this transformation is a familiar one: it is the cumulative distribution function (CDF). A continuous CDF is defined as an integral, so the transformation is

An analytics how-to for small and midsize manufacturers

Small and midsize (SMB) manufacturers are critical drivers of innovation and productivity, and agility often gives them a competitive advantage over larger organizations. But they have unique challenges compared to larger manufacturers who have the resources and capital to achieve greater economies of scale. To take advantage of their agility,

Simulate correlated variables by using the Iman-Conover transformation

Simulating univariate data is relatively easy. Simulating multivariate data is much harder. The main difficulty is to generate variables that have given univariate distributions but also are correlated with each other according to a specified correlation matrix. However, Iman and Conover (1982, "A distribution-free approach to inducing rank correlation among

Rank-based scores and tied values

Many nonparametric statistical methods use the ranks of observations to compute distribution-free statistics. In SAS, two procedures that use ranks are PROC NPAR1WAY and PROC CORR. Whereas the SPEARMAN option in PROC CORR (which computes rank correlation) uses only the "raw" tied ranks, PROC NPAR1WAY uses transformations of the ranks,

Everyone can code with SAS® CodeSnaps

SAS® CodeSnaps is an easy, affordable, and engaging tool. All you need is one iPad, the free CodeSnaps app, one Sphero robot, and a problem to solve. Students work collaboratively in teams to generate the code required to move the Sphero; they build a program using the printable coding blocks, scan it with the app, and execute the program to check their logic. CodeSnaps is accessible and appropriate for all learners across all disciplines. Get creative and challenge your students to navigate an obstacle course, find members of a word family, explore the digestive system, or travel the Oregon Trail. Your imagination is your only limitation.
