Corporate compliance with an increasing number of industry regulations intended to protect personally identifiable information (PII) has made data privacy a frequent and public discussion. An inherent challenge to data privacy is, as Tamara Dull explained, “data, in and of itself, has no country, respects no law, and travels freely across borders. In the digital age, there are no geographical borders. And yet, most governments have attempted to put restrictions on how their citizens’ data is used. When we hear about foreign issues, we treat them like they’re strange and far away, ignoring the fact ... Read More

If you have a random sample from a multinomial response, the sample proportions estimate the proportion of each category in the population. This article describes how to construct simultaneous confidence intervals for the proportions as described in the 1997 paper "A SAS macro for constructing simultaneous confidence intervals for multinomial proportions" by Warren May and William Johnson (Computer Methods and Programs in Biomedicine, p. 153–162). Estimates of multinomial proportions In their paper, May and Johnson present data for a random sample ... Read More

When mentioning to friends that I’m going to Orlando for SAS Global Forum 2107, they asked if I would be taking my kids. Clearly my friends have not attended a SAS Global Forum before as there have been years where I never even left the hotel! My kids would NOT enjoy it… but, I think the conference could also be referred to as “SAS Disney World” with all the excitement, new discoveries and fun characters that you can enjoy during those action-packed days. Training at SAS Global Forum 2017 This year I’m especially looking ... Read More

Word association exercises can often be a fun way to pass the time with friends, or it can trigger immediate action – just think of your email inbox and seeing an email from a particular person: your boss, wife, husband or child. The same can be true for information for your organization. A single word can quickly, efficiently and effectively communicate the performance of a company’s metric, hence the value ... Read More

Much of today's blog discusses basic PROC SGPLOT functionality, but there are a few advanced topics too including how to create piecewise polynomial splines. I will illustrate the REG, PBSPLINE, LOESS, SERIES, and SPLINE statements in PROC SGPLOT. I will also mention the GROUP= and BREAK options in the SERIES statement, which enable you to display separate functions for different groups of observations. The Sashelp.ENSO data set provides a nice example of a nonlinear ... Read More

After the recent presidential election, I was updating my graphs of the voter registration data and noticed that the number of registered voters decreased after the election. At first I thought that was odd, but then I realized that maybe inactive voters were being purged. I wanted to find out more about this, so I rolled up my sleeves and got elbow-deep into analyzing the data... And to get you in the mood for this topic, here's my friend Trena who is an avid voter: Here in North Carolina (NC), the ... Read More

It evokes visions of restrictions, regulations and security protecting something which is to remain private. The term open is most often associated with access, and it evokes visions of an absence of restrictions, regulations and security – making something available which is to remain public. Based on these concepts, it would seem safe to assume you could not be open and compliant at the same time. Let’s examine that assumption in relation to compliance within data management, governance and – specifically – privacy ... Read More

Feed: SAS BlogsRSS – SAS Blogs. Author: Rick Wicklin. A common question on SAS discussion forums is how to repeat an analysis multiple times. Most programmers know that the most efficient way to analyze one model across many subsets of the data (perhaps each country or each state) is to sort the data and use a BY statement to repeat the analysis for each unique value of one or more categorical variables. But did you know that a BY-group analysis can sometimes be used to replace macro loops? This article shows how you can efficiently run hundreds or thousands of ... Read More
