Last edited by jfdinneen; at A consistent, satisficing approach is sufficient. Sorry for bumping a very old thread to the top as my first post on the forum. I found it useful to use a 2D array for exacta prob. Hi John, Yes I definately changed that because I used your equation and then I also did each stage in excel seperately.

These are totally unrealistic assumptions but they do give reasonable values. It is mainly about the authors method of place and show betting which requires them to compute Harville probabilities. Harville in Journal of the Amer.

Correcting this way is formuula a sweeping assumption and is not based on any evidence – just unproven economist theory. My coefficients for place and show in my model are different than the. Also the Shin probability formula for adjusting for fav-longshto bias.

Looking forward to reading and contributing more here, some of the old threads hold a lot of value. Find More Posts by jfdinneen. These days it seems harvville more difficult because the money bet off-track is not added to the tote board until after you can no longer make a bet.

The most relevant one is:. Harvillf 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 why.

I’m not sure if jfdinneen or mwilding are still about, or if harcille else can help, but I decided to try in excel the formulas jfd contributed so generously below.

I have the original henery formula which is very complex as I am sure you know but hadn’t beena ble to get the revised one, so thank you very much.
