Hi Philippe,
I thought I would share some interesting data/results.
Some German casinos put their nightly roulette results on line, spin by spin in time order. You can get years of results if you want.
Here is one casino:

Hi Philippe,
Thanks for taking the time to answer this.
Your response has been very helpful.
By consistent I meant the same output with the same input.
It looks a bit like a monte carlo run where there is variation in output, but you explained it very well.
I will post what I am using it for a little later today, then you will see what I mean.
Regards,
Tom Berger

Arthur,
Leighton Vaughan Williams is based in the UK and used to have a blog.I think he called himself the Betfair Professor. He had access to some studies.
Another tip is also to get Google Scholar and type in various search terms such as tennis market efficiency, favourite longshot bias, and market bias.
Tennis has a few great papers on the favourite longshot bias.
Good luck.

Hi Philippe,
I did work on the horses and greyhounds in the 80's and 90's with fairly primitive software and computers compared with what is available today. The problem is that the market is SEMI efficient, meaning that not all the information is in the prices, but MOST is. This makes the public fairly accurate in predicting winners.
So to be more accurate than the public, a LOT of data is

Hi Philippe,
Thank you for writing an amazingly useful article on visualising the output of SPMF using graphviz.

I was able to replicate your FIFA results using your Java script. However, what I dont understand is what it is doing. It is "condensing" or shrinking t

Hi Phillipe
I have read your papers on authorship attribution. I am interested in the output of TKS -- how you rank the most likely candidate.
It seems you are using a script or customised software to apply the output of TKS to create percentages, discard most common sequences and rank the most likely candidates. Is this script/program available or is it propriety?
I have output TKS from 8

Hi Philippe,
Here is the basic version of a BAT file that will process multiple .text files with TKS in a folder. For simplicity there is no directory checking, so SMPF and the .text files need to be in the same folder.
for %%f in (*.text) do (
echo %%~nf
java -jar spmf.jar run TKS "%%~nf.text" "%%~nfOutput.txt" 50 1 4 "" 1 0
)
That's it!
Hope it

Thanks for your response, Philippe. You gave me a clue by mentioning a Bat file for windows. I did a bit of research and managed to get one running which will process all the files in a folder. It works like a charm! Thanks again.

Good morning,
I am experimenting with skipgrams and TKS. The results are very impressive in text files that I am using. I am wondering if it is possible to batch process a whole folder of txt files instead of entering the input files one at at time in SPMF. Many thanks, Tom
