## Beyond SAS Basics: Tips, Statistics and a Naked Mole Rat

I wanted to learn how to use smashwords, for reasons completely unrelated to this blog, SAS or statistics, but I thought it would go much faster if I had an actual project to work on. I considered writing a serious book for researchers on SAS Enterprise Guide, but then I decided that I did not…

## Math Education Software has a Long Way to Go

I was very busy this weekend working on the semi-annual site update (I am SO getting last place in the Search Engine Optimization contest) and starting on my book – Beyond SAS Basics: Tips, Statistics and a Naked Mole Rat and on TOP of all of that, I had to take the world’s most spoiled…

## Multicollinearity statistics with SPSS

“Can you explain multicollinearity statistics?” she asked. Why, yes, yes I can. First of all, as noted in the Journal of Polymorphous Perversity, “Multicollinearity is not a life-threatening condition except when a depressed graduate student employs multiple, redundant measures.” What is multicollinearity, then, and how do you know if you have it? Multicollinearity is a…

## Could our problem with math be we don’t give a rat’s ass?

I’ve been reviewing a number of options for students to learn mathematics. A lot of sources kind of sucked. At best, these sites were just the same old thing, flash cards but on a computer screen, for example. There is nothing terribly wrong with that, but it is hard to imagine that they have any…

## The rumors of our sucking at math have been greatly exaggerated

Question authority. Whenever I hear authoritative statements made that don’t fit with the world I see around me, I try to follow up. How many times have we been told that the U.S. is just terrible in math, we are falling behind educationally, China and India are eating our lunch – deservedly so, because our…

## Annoyances with SAS that Don’t Exist in Ruby

Now, I’m not as extreme as the person who created a SAS Tetris game, (Richard DeVenezia, in case you were wondering) but I still try to do just about everything in SAS,  if only to prove that I can do it. Why would someone who has been using SAS for 28 years decide to pick…

## How to Get Started in the Consulting Business

“How do you get business?” I get asked this a lot, and since I doubt random people I meet at conferences are truly interested in my life, I think what they really want to know is: “How can I get business as a consultant?” I’ve been working as a consultant for over thirty years. Here…

## Wilcoxon, Normality, Paired T-test & Smart Boys

Lately, I’ve been missing some of my former colleagues at the USC Medical School. This is not just because they are super-nice people, which they are, but also because they used to ask for different types of statistics, and I do think variety is the spice of life – except for in marital relationships where…

## What I learned about statistics from martial arts

I’m doing a workshop at the San Diego SAS users group meeting on Wednesday and  had suggested opening the session with a clip of my daughter’s last amateur fight.  Someone politely commented, “Uh, I guess that would be okay, if it was, uh, relevant.” Fair question, how can martial arts be related to statistics or…
