In this post the football model is programmed into JAGS. There are all the reasons to do so. Jags 3.3 is recently released, I was stimulated by Gianluca's post . Obviously I could copy the model in his paper, but that would be too easy a...

In the previous entry an ordinal model for football games was developed. It is now time to look a bit better at the model and use it. This means three sections; A look at likelihood and link function, a model interpretation part, which focuse...

On September 19th, flo2speak remarked under a post that his/her experience is that ordinal models had better performance. That seems reason enough to try, so there we are. In examining this type of model it is found that more complex models can be...

After reading data, making a predictions display and building a football data model it is time to put this to validate a bit more (regression plots) and put to usage. It appears that the regression plots in the car package were not ...

After reading Dutch football data (Eeredivisie 2011-2012) and making a predictions display it is time to look at a few simple models to predict goals. To reiterate the data setup, each game played consists of two rows in the data frame. ...

Having looked at the football data earlier, I wanted to look at predictions for new games. This consists of two parts, getting a predictive model, predicting and displaying the predictions. I decided to do this backwards, first to make the displays. Th...

The football season has started in Netherlands, so I went and had a look at last year's scores. I did not find downloadable data, at http://www.eredivisiestats.nl/wedstrijden.php I could copy last season's data and paste into a spreadsheet. T...

I am reading Introduction into mixed modelling by N.W. Galway. It is partly a repeat of things I know, but I expect to use mixed models quite a lot the coming time, so it is good to repeat these things.My problem with this book is a sensory exampl...

In my previous post I tried building Williams designs in R. Since that code was running a bit slow, this was an ideal test for Julia. Big enough to be at least slightly realistic, small enough that it is doable.I am very impressed. Almost twenty fold s...

In a previous post I created small Williams designs for an even number of products. This worked very well, also because the number of permutations could be restricted significantly due to symmetry. Unfortunately this does not work so well with an odd n...
