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…
Intimidated by your latest programming task? Code taking longer than you think it should? Here’s a tip – When I was in college, flow charts were what the “cool kids in computer science” did – a phrase Darling Daughter Number One has informed me is oxymoronic. Seriously, when I took Fortran and Basic in school…
My saga on uploading and reading an older data set into SAS Web Editor 1. Use FTP to upload So, I did get my data uploaded to SAS Web Editor using ftp. Little hint here, if you are using Filezilla and having trouble connecting, check to make sure that Filezilla is not using sftp. Sometimes…
After dropping The Spoiled One off at the beach and setting a personal best for calls returned, I’m back on setting up data sets, assignments and more for the fall semester. So ….. I tried using the UPLOAD option from the menu in the SAS Web Editor and that was a sad failure. Next, I…
With three children under age six while I was writing my dissertation, I learned never to leave things until the last minute because that is EXACTLY when two of them would come down with the chicken pox. That’s why I’m working on assignments, lectures and videos for fall semester now. I was asked to teach…
Last week I wrote a bit about how to get an exploratory factor analysis using Mplus. The question now, is what does that output MEAN ? First, you just get some information on the programming statements or defaults that produced your output: INPUT READING TERMINATED NORMALLY Exploratory Factor Analysis ; SUMMARY OF ANALYSIS Number of…
Previously, I discussed how to do a confirmatory factor analysis with Mplus. What if you aren’t sure what variables should load on what factor? Then you are doing an exploratory factor analysis. Really, you should probably do the exploratory factor analysis first unless you have some very large body of research behind you saying that…
Someone had a question about factor analysis with Mplus and even though it is not a piece of software I work with normally, we aim to please at The Julia Group, so I downloaded the demo version and away I went. It truly was, as my granddaughter says, easy-peasy lemon squeezie. You might not think…
If that sounds like total marketing b.s. to you, I can’t blame you — download this app and supermodels will throw themselves at you with thousand dollar bills in their teeth. Well, no super models are provided but the SAS Web Editor really *will* write your code for you in the latest version soon to…
Trying this live blogging from SAS Global Forum again. The title kind of says it PROC QUANTLIFE new procedure in SAS 9.3 Why DO we need a new procedure for survival analysis? ====== Survival analysis used to analyze time-to-event data already had procs lifetes, lifereg & phreg ======== Lifereg is fine if you have IID…
