Deming regression (also called errors-in-variables regression) is a total regression method that fits a regression line when the measurements of both the explanatory variable (X) and the response variable (Y) are assumed to be subject to normally distributed errors. Recall that in ordinary least squares regression, the explanatory variable (X)

They've been begging you for deeper insight into customer data to better serve their callers. They want to know which customers
Last year, I wrote more than 100 posts for The DO Loop blog. Of these, the most popular articles were about data visualization, SAS programming tips, and statistical data analysis. Here are the most popular articles from 2018 in each category. Data Visualization Visualize repetition in song lyrics: In one
Joyce Norris-Montanari discusses data engineers in the second of her two-part series.
This post rounds out the year and my series of articles on SAS REST APIs. You can read all of my posts on this topic here. The first two articles in the series: Using SAS Viya REST APIs to access images from SAS Visual Analytics and Using SAS Cloud Analytics
By now, we're all aware of the seismic shift occurring across industries as a result of the Internet of Things. But do we all see the changes in the same light? From where I sit, there's still a wide gap in viewpoints and perspectives. In its simplest form, we often
The ODS Graphics software, first released with SAS 9.2, supported creating graphs directly from statistical procedures. Prior to this, very few statistical procedures created graphs on their own, and in most cases creating graphs was a post process or creating the graphs from the saved data using SAS/GRAPH procedures. With
Today's guest blog is the second of two on the topic of helping an older parent downsize and relocate. The author, Jennie Alwood, is the owner of Here2Home, a senior move management company in the Triangle area. In Part 1 we looked at getting our minds around the
Good news -- the SAS program that you wrote and put into production 10 years ago still works. Hey, it's SAS, so you probably take that for granted. But are those techniques from 2008 still the best way to accomplish your task? SAS 9.4, first released in 2013 and now
Across the business world, software as a service (SaaS) has redefined the way that people think about licencing software. In the past, licencing enterprise software was a major undertaking, but now the time-to-value has dropped from months to days. The trade-off is that organizations that buy SaaS will get an
Well SAS, you outdid yourselves once again! For 7 years running, we've been collecting and donating leftover and excess Halloween candy from SAS families. After last year's record breaking 580 pounds of donated candy, we challenged you to raise the {candy} bar even higher this year...and man did you do that,
Staff parties, holiday treats, indoor snow days, the list of welcomed distractions continues. This time of year is full of festivities that call for our attention. The choices can be daunting at times. Sometimes they derail us from our plans and progress. What can you do to manage the madness?
I regularly see questions on a SAS discussion forum about how to visualize the predicted values for a mixed model that has at least one continuous variable, a categorical variable, and possibly an interaction term. SAS procedures such as GLM, GENMOD, and LOGISTIC can automatically produce plots of the predicted
Encouraging data sharing can sometimes feel like refereeing kids on Christmas morning. “Mom said you have to SHARE!” my sister bawled, grabbing at the Game Boy in my hand as I held the toy just out of her reach. I had just gotten it as a Christmas present and had
SAS for Mixed Models: Introduction to Basic Applications takes you step-by-step through the journey of creating models, enabling you to transform scores of data into actionable insights.

Many data analysts use a quantile-quantile plot (Q-Q plot) to graphically assess whether data can be modeled by a probability distribution such as the normal, lognormal, or gamma distribution. You can use the QQPLOT statement in PROC UNIVARIATE to create a Q-Q plot for about a dozen common distributions. However,
Singer-songwriter David Wilcox kept me out of prison. That’s not a country song gone bad – it’s a real-life experience. Almost two decades ago, I attended a David Wilcox concert in downtown Raleigh, North Carolina. His songs have always hooked my heart, and one in particular caught my attention that
Every so often, SAS Technical Support highlights questions that come in on a regular basis. This is one of those times. Here Kim Wilson describes answers to questions covering SAS dates, arrays, and how to reference local PC files from SAS® Enterprise Guide® and SAS® Studio when those applications connect to a SAS® server in UNIX operating environments.
Certain North Carolina counties have been in the news lately, for suspected election fraud involving absentee ballots in the 2018 election. Let's analyze the voter registration and absentee ballot data, to see if we can detect anything suspicious! In order to definitively determine whether fraud & illegal activity occurred, investigators
By now you’ve seen the headlines and the hype proclaiming data as the new oil. The well-meaning intent of these proclamations is to cast data in the role of primary economic driver for the 21st century, just as oil was for the 20th century. As analogies go, it’s not too
The data revolution is causing disruption everywhere. Even governments are feeling the effects. While the public sector may be less prepared for the impending changes, government has good reasons to embrace the data revolution. First, governments have been collecting data for years. They have lots of data. This supports programs,
