My heart goes out to whoever is writing the blog, “My start-up has 30 days to live”. It’s the truest thing I’ve read about business since Paul Hawken wrote that the reason most small businesses fail is that they have too much money. It’s funny, because I was on the Forty Women to Watch over…
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…
“The problem with women isn’t that they leave you, but that they have to tell you WHY.” Whether in teaching judo, statistics, programming or management, I’m a big fan of telling people why. As I said before, the first step in programming is to THINK. This applies to statistical programming as well, which is what…
How we refer to older women in our language would be translated literally as “the one who holds things together”. Yet, we have forgotten that in the modern world. We are no longer proud of our grey, we hide it with dye in our hair. We go to aerobics classes to try to keep the…
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…
If you have not listened to the TED talk by Conrad Wolfram, I highly recommend you do. If you have any interest in math education, the odds are great that his talk is far more important than anything else you could possibly doing in the next 20 minutes. If you think the name sounds familiar,…
Do yourself a favor and read this terrific post, The 10 Biggest Mistakes I Made as a Start-up Founder. Given the miasma of bad start-up advice out there, this post is a breath of fresh air in a pollution of stupid. The Julia Group is doing well, and our latest venture, 7 Generation Games, which…
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…
The Mplus website has free videos on using Mplus. The introductory course (not very introductory, really, because the the main topics are advanced factor analysis and structural equation modeling) has some pretty good resources. While it is not professional quality – just a video of a class – and much of it is beyond the…
