Am I missing something here? All of the macros I have seen for the parallel analysis criterion for factor analysis look pretty complicated, but, unless I am missing something, it is a simple deal. The presumption is this: There isn’t a number like a t-value or F-value to use to test if an eigenvalue is…
I was reading a book on PHP just to get some ideas for a re-design I’m doing for a client, when I thought of this. Although I think of PHP as something you use to put stuff into a database and take it out – data entry of client records, reports of total sales –…
Today, I was thinking about using data from the National Hospital Discharge Survey to try to predict type of hospital admission. Is it true that some people use the emergency room as their primary method of care? Mostly, I wanted to poke around wit the NHDS data and get to know it better for possible…
One definition of insanity is doing the same thing over and over, expecting different results. One thing that can drive programmers insane is doing the same thing over again and GETTING different results. In a past life, working in tech support, I learned that whenever anyone calls and says, I did it exactly like your…
When I was running out to the airport, I said I would explain how to get a single plot of all of your scatter plots with SAS. Let’s see if I can get this posted before the plane lands. Not likely but you never know … It’s super simple proc sgscatter data=sashelp.heart ; matrix ageatdeath…
My life is upside down. All day, as my job, I spent writing a program to get a little man to run around a maze, come out the other end and have a new screen come up with a math challenge question. Then, in the evening, I’m surfing the web for interesting bits to read…
I’m pretty certain I did not deliberately hide these folders. When I opened up my new and improved SAS Studio, it had tasks but my programs were missing. If this happens to you and you are full of sadness missing your programs, look to the top right of your screen where you see some horizontal…
I’ve been pretty pleased with SAS Studio (the product formerly known as SAS Web Editor), so when Jodi sent me an email with information about using a virtual machine for the multivariate statistics course, I was a bit skeptical. Every time I’ve had to use a remote desktop connection virtual machine for SAS it has…
Sometimes the benefits of attending a conference aren’t so much the specific sessions you attend as the ideas they spark. One example was at the Western Users of SAS Software conference last week. I was sitting in a session on PROC PHREG and the presenter was talking about analyzing the covariance matrix when it hit…
I’m just heading off to the Western Users of SAS Software meeting that starts tomorrow. After the keynote, during which I have promised not to swear even once, I’m doing a SAS Essentials talk on Thursday, where I teach students 10 basic steps that allow them to complete an entire annual report project. One of…
