A while ago I saw a blog post on how to simulate Bernoulli outcomes when the probability of generating a 1 (success) varies from observation to observation. I've done this often in SAS, both in the DATA step and in the SAS/IML language. For example, when simulating data that satisfied
Often we have the need to see the data by two different classifiers at the same time, as requested by a recent query on the SAS Communities page. In this example I have simulated a response over time for patients by study and treatment. We want to create series plots
The increasing use of predictive analytics in mission-critical business decisions and operations brings new challenges to the forefront for many of our customers. Throughout the last year I spoke to many customers about their use of predictive analytics and where they see areas of improvement to achieve even more success
Anything that you do manually leaves the door open for error; this is especially true for your file system. Aside from that, automated processes are usually faster. Magnus Mengelbier has applied this philosophy to providing version control capabilities to SAS data sets, programs and outputs.
Being that 2013 is the International Year of Statistics, I wanted to make sure everyone knows how to handle my favorite statistic - percent (%) - in SAS! I often see data in spreadsheets/csv/etc that purport to represent "percents"... but you have to be a bit careful when working with
In version 4.3 of SAS BI Dashboard, data caching is not enabled by default. Each time a user opens a dashboard, each element on the dashboard executes a query to return the result. Enabling data caching can improve dashboard performance by generating data results in advance.
Happy 2013, it’s hard to believe another year has passed! New Year’s is typically a time for new beginnings and for many people New Year’s Resolutions. How many years have you vowed on January 1st to start eating healthier, lose weight, or hit the gym more? And how often have
I've bragged about how easy it is to install custom tasks for SAS Enterprise Guide. It's simple: you copy the .NET assembly (usually a single DLL file) into one of the designated folders in your SAS Enterprise Guide installation, and your task just shows up in the menu. Since I
The creation of Health Information Exchanges (HIEs) took off in 2009 with the establishment of the State Health Information Exchange Cooperative Agreement Program (SHIECAP). Recently, it seems like HIEs have been somewhat of the middle-child, garnering less attention between the health insurance exchanges and Medicaid expansion. But let’s take a
I am pleased to announce that this year at SAS Global Forum 2013 (San Francisco, April 27 to May 1, 2013) I am giving a free hands-on workshop (HOW) entitled "Getting Started with the SAS/IML Language." If you are not familiar with the very popular Hands-On Workshop series at SAS
OK, I promise this is the last article on Forest Plots (at least for a while). In the previous article on Subgrouped Forest Plot with Font Attributes, I discussed how to use bold text for subgroup headings. I mentioned that increasing the font size would not work as it would
Just a few days ago our "super-duper tech support trooper" called in asking for the link to the subgrouped Forest Plot with bold headings. She was referring to this Forest Plot with Subgroups I had posted earlier. However, as you can see, while the subgroup values are indented from the subgroup headers, the headers
Many of my blogging colleagues are taking this week to reflect on their top posts in 2012. Some are using the visitor statistics to rank the posts, but as Andy Ratcliffe points out, that gives short-shrift to the late-season articles. This year, I'm going to use this space to recap
In the spirit of the new year – the International Year of Statistics – I thought I’d share some different ways to use statistics. Can statistics help you in your everyday life? Certainly! And here's an example to prove it... Let's say you have a dresser drawer full of white socks.
It's the start of a new year. Have you made a resolution to be a better data analyst? A better SAS statistical programmer? To learn more about multivariate statistics? What better way to start the New Year than to read (or re-read!) the top 12 articles for statistical programmers from
