Since it is the weekend, I decided to blog about weekend stuff. Look for more statistics tomorrow. For most of the past quarter-century, I have been roped into being a volunteer for one organization or another. Here is a very, very partial list: American Association on Mental Retardation National Council on Family Relations United States…
Ever wonder why with goodness of fit tests non- significance is what you want? Why is that sometimes when you have a significant p-value it means your hypothesis is correct, there is a relationship between the price of honey and the number of bees, and in other cases, significance means your model is rejected? Well,…
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 –…
I’ve been looking high and low for a supplemental text for a course on multivariate statistics and I found this one – The Multivariate Social Scientist, by Graeme Hutcheson 7 Nick Sofroniou They are big proponents of generalized linear models, in fact, the subtitle is “Introductory statistics using generalized linear models”, so if you don’t…
I find it weird when I make people nervous. I’ve had people shake and stutter so much that I thought they had some sort of disability, only to find out later that it was a reaction to meeting me! My family and friends say I’m intimidating, which I also find bizarre. I am, literally, a…
You might have gotten the misimpression from my previous post that I don’t think students need to learn all that much matrix algebra that I am a slacker as far as expecting students to come to courses with some prior knowledge. That’s not exactly the case. In fact, here are some things I just assume…
Every day, every week, I face the same question that all entrepreneurs ask themselves – “How do you know when you are done?” Most days, I start work around 10 am and finish about 14 hours later. Usually, I take off an hour for lunch and an hour for dinner, or take a few hours…
Following a discussion using matrix algebra to show computation in a Multivariate Analysis of Variance, a doctoral student asked me, “Professor, when will I ever use this? Why do I need to know this?” He had a valid point. I’m always asking myself why I’m teaching something. Is it because it interests me personally, because…
I’m pretty certain that I’m a woman in technology. Last night, I was using SAS on a virtual machine through a remote desktop connection to prepare data from the National Hospital Discharge Survey for use in examples of MANOVA and multinomial logistic regression. Today, I was working on improving animation in the Javascript for a…
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…
