Sometimes the simplest things can make life easier. When I start exploring a new data set, the first thing I do is the Characterize Data task. With even modest-sized datasets this produces a lot of output. For example, the data from Spirit Lake: The Game, with about 80 variables and 88 subjects produced 93 pages….
I’m doing a Hands-On Workshop in Las Vegas at the Western Users of SAS Software conference in November. When they asked me for some topics, I thought about factor analysis or categorical data analysis, but I’m already doing a couple of other talks on those procedures. I really felt like one of the most overlooked…
A two-by-two table is a very common design. The column variable is some type of treatment or intervention. For example, older (over 65 years of age) people who either lived in a nursing home or who did not. Your row variable is some categorical outcome. For example, they either lived or died. You create a…
After installing the latest version of SOD with Enterprise Guide 6.1 on Virtual Box and finding it really slow, I decided to re-install the operating system I had on bootcamp to upgrade to 64-bit and see if it ran better native. When I downloaded the file to install it said it was not compatible with…
I’ve been working with SAS Enterprise Guide 6.1 with SAS On-Demand on Virtual Box and I can’t find much to complain about. It is slow, but since I’m usually doing 14 things at once, while I’m writing for a task to complete I can read an email, download a file or answer a phone call….
There was supposed to be a new SAS On-Demand in June so I put off downloading the latest version to prepare for my fall courses. When I went to download SAS Enterprise Guide, however, I saw that the upgrade had been postponed until July. Not sure what that will entail but since I had recently…
I was working on something for a client when The Invisible Developer walked into my office, looked over my shoulder at the code and said, “So, you’re a PHP programmer now?” I answered, “I’m a whatever-language-we-happen-to-need-at-the-moment programmer.” A year and a half ago, I took a look at Codecademy and was underwhelmed. It’s gotten mixed…
So, yesterday, if you were paying attention, we figured out WHY to do a factor analysis today’s post is about how. I’m using SAS Enterprise Guide because I had it open on my computer. Here is what the completed project looks like: Here is what I did, reading from the top — I opened…
Too often, when I look at the surveys some people design, I have the same thought as when I see my granddaughter with a lollipop bigger than her head – Just what exactly do you think that you are going to DO with that? The problem is that both may have metaphorically (or, in Eva’s…
Spirit Lake: The Game is mostly an adventure game that teaches math. However, it has lots of Easter eggs, side quests and spin-offs added because hey, these are kids and sometimes they like to do something different and some of them have the attention span of an ant. Our idea is to make the game…
