So far, we have looked at How to get the sample demographics and descriptive statistics for your dependent and independent variable. Computing descriptive statistics by category Now it’s time to dive into step 3, computing inferential statistics. The code is quite simple. We need a LIBNAME statement. It will look something like this. The exact…
In the last post, I posed the following null hypothesis as an example: There is no difference in obesity among Caucasians, African-Americans and Latinos. You can see the results from the statistical analyses here. Since my question only pertains to those three groups, let’s begin by creating a data set with just those subjects. libname…
I get asked this question fairly often so I thought I would do a few posts on it. The most common problem is that a student who is new to statistics has no idea where to even start. These examples use SAS but you could use any package you like. My recommendation to students beginning…
First off, the good news. You can find all of the papers from SAS Global Forum 2015 online. This is good news if you are anything like me (and you should be, because, let’s face it, I’m awesome) because even if you went to Dallas there were no doubt several papers you wanted to attend…
Great! You are using SAS Studio. It’s free. Even greater. You cleaned your data, created subscales. You have this perfect dataset and now, you want to save that dataset to your desktop and maybe do some more work with it, or just open up and admire it – who am I to judge? Follow these…
I finally am getting around to something in SAS Studio that I think is really cool – the tasks. Although they don’t look identical to SAS Enterprise Guide just because the screen layout is a little different, these are really, really similar to the tasks you would see in EG. If you are using this…
Why? Are you kidding me? If you are a programmer, analyst, statistician, professor or student who uses SAS this is an opportunity to get to know your people and to get known. I’m in Dallas for the SAS Global Forum, which I try to attend whenever I can. Yes, I could watch videos on the Internet,…
It has been pretty well established that I am the worst soccer mom in the history of soccer moms. Most of the games I miss because I am somewhere else. My children have told me that my autobiography should be entitled, “I was out of town at the time” because most of the stories of…
I’m giving a talk on Preparing Students for the Real World of Data at SAS Global Forum next month. You’d think 50 minutes would be long enough for me to talk, but that just goes to show you don’t know me as well as you think you do. One point made in the template for…
If you came into my office and watched me work today, just before I had you arrested for stalking me, you might notice me doing some things that are the absolute opposite of best practices. I need about 10 datasets for some analyses I’ll be doing for my SAS Global Forum paper. I also want…
