The difference Equations that arise turn out to be quite easy to solve by iterations , and they have very nice closed forms . I will go on and put some values on some of the parameters so that the final outcome for the set of orthogonal

Since the seminal paper by Darroch , Lauritzen Speed 1980 these techniques have been widely used to model as well as discover the multivariate dependence independence structure of a set of variables . Nowadays , the theory of graphical models is well-established and provides a rich set of statistical tools for modelling the complex relationships among variables see Wermuth Sadeghi

  • Ordinary Differential Equations and the Laplace Transform

    Updated: 2012-08-21 00:44:40
    Introduction Down the road, I expect to be using Laplace transforms to set up and solve electric circuits, and for transfer functions in control theory. An obvious starting point is to remind you just what a Laplace transform is. So I should show you at least one example of solving a differential equation using Laplace [...]

  • Taking Sudoku Seriously

    Updated: 2012-08-20 21:01:21
    I received the book Taking Sudoku Seriously by by Jason Rosenhouse and Laura Taalman for review and put it aside to collect some dust. You see, I have solved too many Sudokus in my life. The idea of solving another one made me barf. Besides, I thought I knew all [...]

  • Happenings – 2012 Aug 18

    Updated: 2012-08-18 20:15:09
    I was out of town on business for most of the week… and I didn’t take any math books with me. It feels like forever since I’ve even looked at math. We’ll see what happens today. I’d like to have some fun. I don’t sleep well in hotels in general, nor in other time zones… [...]

  • Books Added – Regression and Statistics

    Updated: 2012-08-14 00:19:09
    The following books have been added to the bibliography. Atkinson, A.C. Plots, Transformations and Regression. Oxford Science Publications, reprinted 1988. ISBN 0 19 853359 4. [regression; 13 Aug 2012] This is devoted to detecting outliers (i.e. using single deletion statistics) and to transformations of the variables. It looks like an excellent supplement to Draper and [...]

    Updated: 2012-08-11 16:46:40
    It’s been about as slow a week as I’ve ever had… I couldn’t even justify a headlines ticker-tape today. My alter ego the kid has been looking at surfaces again… my alter ego the grad student has been looking at so-called “arithmetic functions”. My main personality is thinking I should elaborate on the latest regression [...]

  • Judging the Tail

    Updated: 2012-08-09 23:07:14
    It’s easy to judge who is the fastest runner or swimmer. Judges do not need to be runners and swimmers themselves. They simply need a stopwatch and a camera. Other competitions are more difficult to judge. Take for example the Fields medal. The judges need to be mathematicians. Since they can’t be [...]

    20 Aug 2012 Edit: The differential equations book did have material on Heaviside’s operational calculus! What I’ve got for today’s post is little more than headlines. Perhaps what I need today is a ticker tape running across the bottom of my homepage. Roger Federer and Andy Murray will play for gold and silver medals tomorrow. [...]
