Last edited by jfdinneen; at Michael, As you say, it does not make any sense. I just clicked one on of the links “how not to be wrong Michael, Did you remember to change the prob H3, wins value from 0. Please check for errors. I am getting a different result to you though when i do it manually and I can’t work out why. What I am doing is 0. Choose a web site to get translated harvills where available and see local events and offers.
A consistent, satisficing approach is sufficient. John Thanks for the update.
Leave for 24 Hours? Michael, Apologies for not replying sooner but I have not logged on to the forum for a couple of days. Is anybody able to tell me these formulas or point me somewhere I can get them? Sorry for bumping a very old thread to the top as my first post on the forum. The following code implements the formula: Thanks for the reply.
Home Questions Tags Users Unanswered. I remember at least one attempt to use another formulq like Harville, but with normal random variables instead. In your program you should get 0. I’m not sure if jfdinneen or mwilding are still about, or if anyone else can help, but I decided to try in excel the formulas jfd contributed so generously below. I can’t see any reason for this though!!

I have included the “informed Factor” harvi,le into my bet size calculations. I have included it in the last 35 races and it improves the results let’s see how long that last.
Just had time to go through the top place equation. Sorry for bumping a very old thread to the top as my first post on the forum. Also the Shin probability formula for adjusting for fav-longshto bias.
Post as a guest Name. Isn’t that the normal Harville formula though, I understood that the discounted Harville was a modification of this to help counter the problem that as you say a horse may have no chance of winningbut high of placing or high chance of winning and none for placing.
Spot 2, 4 9. Spot Jun 22 ’14 at 6: Hi John, Thank you very harvil,e. The authors provide a table of intermediate values for both lambda and rho but, personally, I have found that the Henery values are satisfactory.
This is all based on individual win probabilities as the starting point. So am I right in understanding that if you are using your own probabilities then use the.
Looking forward to reading and contributing more here, some of the old threads hold a lot of value. SInce there are horses who have a good prob. The most relevant one is:.
