Michael, The “Discounted Harville” formulae, as requested Excel-like syntax – check accuracy: Spot 2, 4 harvillee. So am I right in understanding that if you are using your own probabilities then use the. And then they adjust the Harville values based on a regression with track data.

It is mainly about the authors method of place and show betting which requires them to compute Harville probabilities.

Change Prob H3, wins from 0. John Although I did not find the spreadsheet that JF Dinneen mentioned, I am much more interested in that blog site itself. It appears that Google deleted the original “Harville” spreadsheet from the blog some time ago, without requesting my permission? However the sum of these probabilities does not add to one. Thanks for the reply. The code to calculate P2nd returns 0. I remember at least one attempt to use another model like Harville, but with normal random variables instead.

What I am doing is 0. Just had time to go through the top place equation. SInce there are horses who have a good prob.

What you are using is known as Harville’s method. I am getting a different result to you though when i do it manually and I can’t work out fomula.

Sorry for bumping a very old thread to the top as my first post on the forum. Placing probability depends far more on the horses involved in a race than dormula the maths. The exacta formula works a treat, but somehow I cannot get a sensible result out of the trifecta formula.

I have included it in the last 35 races and it improves the results let’s see how long that last. For some reason that I still don’t understand, when I do it seperately I get the figure differently to you and it changes at the point above. Home Questions Tags Users Unanswered.

The exacta formula works a treat, but somehow I cannot get a sensible result out of the trifecta formula. Note that tractability issues arise because you have to sum over all exactas rormula H2 places in order to calculate the H2 place probability. Copyright – harvillf PaceAdvantage. I inadvertently added an additional SUM term to both equations in my original repy – apologies – never post mathematical equations to forum late at night!
